We are committed to the safety of our customers, business partners, and employees.

As a distributor that directly supports the continuing operation of critical facilities in the healthcare industry, food & agriculture industries, power industry, and other infrastructure industries, our facilities and operations will remain open during the Wuhan Coronavirus pandemic until further notice.

Our Golden, CO  head office and warehouse remains open and our supply chain remains intact. We are maintaining a limited staff in our office  to support critical functions including shipping/receiving, accounting, and IT.  We have also implemented a rotating remote work schedule to minimize employees at the office at any specific time.

Additionally, we have implemented the following requirements:
  • Restricting visitor access to our facility.
  • Increased frequency of sanitizing facilities and workspaces.
  • Requiring regular hand washing and sanitizing.
  • Using technology where possible to replace in-person meetings.
We will update this statement as the situation changes.

We thank you for your continued business and support. Please stay safe and be well.

Flo-Tite Sentinel Segmented Control Valve for Severe Service Applications


The Flo-Tite Sentinel is an ideal control valve for severe service applications where precise control is required for clean or dirty liquids, gases, and fibrous suspension applications.

Precise contouring of the V-notch provides excellent control characteristics for an extensive variety of flow applications. An ideal control performance is designed into the geometry of the ball for critical management of flow. A locked ball-to-shaft connection ensures no lost motion during critical control.

Splined connection between the shaft and ball ensures precise control and low hysteresis. Streamlined flow passage provides maximum efficiency and minimizes erosion inside the valve body.

Detachable seat retainer design provides easy access to trim parts of the valves through inlet of valve by simply removing the screws of retainer allowing for easy maintenance. Superior trunnion bearing technology is engineered for excellent abrasion resistance.

Rugged self-adjusting metal seated option is ideally suited for higher temperature applications or slurries. Spring loaded seat maintains constant contact with the ball, providing enhanced sealing performance. Shearing action between ball and seat promotes smooth, non-clogging operation, perfect for fibrous or slurry applications.

Understanding the Various Kinds of Steam Traps

Steam Trap

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 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 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.
