Understanding the Various Kinds of Steam Traps
It is essential, without loss of live steam, to remove condensate and often air and other incondensable gases from steam systems. Knowing the range of steam traps allows the best choice to be made for all applications.
Thermodynamic steam traps
Thermodynamic steam traps combine reliability, simplicity and efficiency of operation; with just one moving part (a hardened stainless steel disc) they give a blast discharge with clean, tight shut-off. They are able to withstand: superheat, water hammer, corrosive condensate, freezing and vibration.
Ball float steam traps
Ball float steam traps are extremely versatile and work efficiently on both light and heavy condensate loads. Although compact in size, their discharge capacity is high and continuous, ensuring maximum heat transfer. These traps are the best choice for draining plant with automatic temperature control.
An integral air vent is fitted as standard and an adjustable needle valve is available as an option to prevent steam locking.
Balanced pressure thermostatic steam traps
Balanced pressure thermostatic steam traps adjust automatically to varying steam pressures and have excellent air venting characteristics during plant start-up and during normal operation. They have large discharge capacities for their size and the robust design of the internals gives a good life expectancy.
Sealed steam traps
Sealed maintenance free steam traps.
Range: balanced pressure, inverted bucket and bimetallic versions.
Inverted bucket steam traps
Inverted bucket traps are the most robust type of the mechanical traps and will resist water hammer. When the check valve option has been fitted in the inlet, they can be used with superheated steam. They are available with a wide selection of valve orifices for precise pressure and load matching.
Bimetallic thermostatic steam traps
Bimetallic steam traps can conserve energy by discharging sub-cooled condensate in those applications which can utilize sensible heat. They are the most robust of all the thermostatic steam traps, being able to withstand water hammer and corrosive condensate.

Valve Actuator Basics
Valve actuators are categorized based upon a number of factors including power source available, torque necessary to operate the valve, installation location, and the need for automatic actuation. Actuators are devices which supply the force and motion to open and close valves. They can be manually, pneumatically, hydraulically, or electrically operated. In common industrial usage, the term actuator generally refers to a device which employs a non-human power source and can respond to a controlling signal.
Types of actuators include:
- Electrical motor
- Pneumatic
- Hydraulic
- Manual handwheel or lever
Electric Actuators
![]() |
Electric Actuator |
Electric motors permit manual, semi-automatic, and automatic operation of the valve. Motors are used mostly for open-close functions, although they are adaptable to positioning the valve to any point opening. The motor is usually a, reversible, high speed type connected through a gear train to reduce the motor speed and thereby increase the torque at the stem. Direction of motor rotation determines direction of disk motion. The electrical actuation can be semi-automatic, as when the motor is started by a control system. A handwheel, which can be engaged to the gear train, provides for manual operating of the valve. Limit switches are normally provided to stop the motor automatically at full open and full closed valve positions. Limit switches are operated either physically by position of the valve or torsionally by torque of the motor.
![]() |
Pneumatic Actuator |
Pneumatic Actuators
Pneumatic actuators are used for automatic or semi-automatic valve operation. These actuators translate an air signal into valve stem motion by air pressure acting on a diaphragm or piston connected to the stem. Pneumatic actuators are used in throttle valves for open-close positioning where fast action is required. When air pressure closes the valve and spring action opens the valve, the actuator is termed direct-acting. When air pressure opens the valve and spring action closes the valve, the actuator is termed reverse-acting. Duplex actuators have air supplied to both sides of the diaphragm. The differential pressure across the diaphragm positions the valve stem. Automatic operation is provided when the air signals are automatically controlled by circuitry. Semi-automatic operation is provided by manual switches in the circuitry to the air control valves.
Hydraulic Actuators
![]() |
Hydraulic Actuator |
Hydraulic actuators provide for semi-automatic or automatic positioning of the valve, similar to the pneumatic actuators. These actuators use a piston to convert a signal pressure into valve stem motion. Hydraulic fluid is fed to either side of the piston while the other side is drained or bled. Water or oil is used as the hydraulic fluid. Solenoid valves are typically used for automatic control of the hydraulic fluid to direct either opening or closing of the valve. Manual valves can also be used for controlling the hydraulic fluid; thus providing semi-automatic operation.
Manual Actuators
![]() |
Manual Operator |
Manual actuators are capable of placing the valve in any position but do not permit automatic operation. The most common type mechanical actuator is the handwheel. This type includes handwheels fixed to the stem, hammer handwheels, and handwheels connected to the stem through gears.
Gear Operators
If additional mechanical advantage is necessary for a manually-operated valve, the valve bonnet is fitted with manually-operated gear heads as illustrated in Figure 32. A special wrench or handwheel attached to the pinion shaft permits one individual to operate the valve when two individuals might be needed without the gear advantage. Because several turns of the pinion are necessary to produce one turn of the valve stem, the operating time of large valves is exceptionally long. The use of portable air motors connected to the pinion shaft decreases the valve operating time.

Introduction to Gas Pipeline Block Station Valves
When a gas pipeline is constructed it is divided up into segments using block valve stations. This enables various sections to be isolated for inspection and maintenance. The block valve is typically a full-bore, soft seated ball valve to allow for "pigging", a practice that includes cleaning and inspecting the pipeline. However, it is not recommended that soft seated ball valves be opened against full differential pressure as damage to the valve seats can occur. To mitigate valve seat damage, a bypass system is installed around the main block valve to balance the pipeline pressure prior to opening. For these bypass requirements, plug valves are commonly used because their inherent design tolerates full differential pressure and allows for the opening and throttling without damage.
Why You Need a Bypass
![]() |
Full port ball valve |
Because the block valve (often is a soft seated ball valve) is exposed to full differential pressure, it faces a huge pressure drop across the valve as it opens. The pressure drop generates high velocity flow, very often accompanied by scale, rust and dirt particles. These particles come in contact with the valve seats resulting in seat erosion and damage. Once the valve seats are damaged, the block valve cannot seal bubble tight once closed. To avoid the block valve seats from being exposed to high velocity, erosive particles, a bypass is utilized to balance the pressure either side of the block valve prior to the opening of the block valve.
Prevention of Block Valve Seat Deterioration Using Bypass Valves
![]() |
Plug valve (CRANE Xomox) |
With the pressure now equalized in the pipeline, the block valve can be opened safely, without the risk of seat damage. Bypass valves 1 & 2 have done their jobs and are now fully closed, providing bubble tight shutoff for the main pipeline.
Pipeline Venting to Atmosphere
Block stations are required occasionally vent a section of the pipeline to atmosphere. This too is a demanding application, with the valve being exposed to full differential pressure. This operation starts with all valves in the system being closed. Bypass valve 1 is then opened allowing pressure into the bypass station system. The vent valve is now slowly opened to release the pipeline pressure. Plug valves are commonly used here again to ensure bubble tight isolation to the atmosphere once closed.

NIVELCO MicroTREK Guided Wave Radar Level Transmitter Training
The NIVELCO MicroTREK Guided Wave Radar level transmitter is designed for continuous level measuring of conductive or non-conductive liquids, pulps and solids. MicroTREK level gauge operates based on the well-known TDR (Time Domain Reflectometry) principle. Micropulses are sent along a probe guide at the speed of light. As soon as the impulse reaches the surface of the medium, it is reflected back to the electronic module. Level distance is directly proportional to the flight time of the impulse.
The video above provides an excellent introduction of the MicroTREK's design, application, and operation.

Crane FKX 9000 Butterfly Valve: Triple Offset Explained
The Crane®FKX 9000 Triple Offset valve design is recommended for industrial applications where large bore valves handle hot steam or isolate parts of their plants and have high/low temperatures that prevent the use of rubber lining elements.
Here's an explanation of "Triple Offset":
Offset One
This offset applies to the center line of the disc/seat sealing surfaces that provides an uninterrupted sealing surface.
Offset Two
This offset refers to the location of the shaft with respect to the center line of the bore, which enables a calming action of the disc to minimize rubbing and wear between the seat and seal.
Offset Three
This offset is the axis of the seat cone angle that is offset from the center line of the valve bore to eliminate rubbing of the seat/seal contact surfaces during operation and to preserve sealing integrity over the cycle life of the valve.
