BS&B FlameSaf Arrester Products


Flame arresters are devices that protect against explosions by preventing the transmission of flame and explosion in machines, equipment, and plants.  These autonomous safety systems limit the effects of the explosions, rendering them harmless. They are intended to allow flow but prevent flame transmission.


A deflagration is an explosive combustion process in which the flames propagate at subsonic velocity. For deflagration, there are end-of-line and in-line deflagration flame arresters. When installing in-line flame arresters, it is imperative to adhere to the ignition source's maximum distance (L).



A detonation is an explosion propagating at supersonic velocity characterized by a shock wave. Detonations occur in pipelines with long distances to the ignition source (L > 50 x DN being an example for explosion group IIA).

An in-line detonation flame arrester's flame arresting capability and mechanical strength are much more significant than an in-line deflagration flame arrester. Devices designed for detonation conditions will provide deflagration protection as well.


Stabilized burning is the steady burning of a flame at or on a flame arrester element. Survival of such conditions requires the selection of an arrester model designed for endurance conditions.

Understanding the Difference Between Trace or a Snap-Action Mechanisms in Pressure and Temperature Switches

Processes can use either a trace or a snap-action switch to provide an electrical response to the rise or fall in pressure or temperature.  

Trace mechanisms, also known as spring-based mechanisms follow or trace the exact pattern of pressure or temperature changes. These trace devices can include a helical spring or spiral spring, a Bourdon tube, or bellows in their mechanism. 

Unlike trace switches, a snap-action mechanism remains inactive during system pressure and temperature changes. When the set-point is reached, the snap-acting disc in the mechanism immediately reacts to activate the switch. Eliminating this ongoing motion until the point of activation and deactivation can reduce the mechanism and switch element wear, extending its duration. 

CCS pioneered the Dual-Snap, snap-action disc used to provide accurate and reliable pressure and temperature measurement under every operation.

API-6A Trunnion Mounted Ball Valves

API-6A Trunnion Mounted Ball Valves

A trunnion mounted valve uses a ball supported by both a shaft and a post opposite the shaft and a seating arrangement using a floating seat. With a mechanically connected ball at the top and bottom pivot points, the process pressure pushes the upstream seat against the ball's sealing surface. 

Trunnion-mounted ball valve applications include pipeline, process, power, oil & gas, and other flow control applications where quality, design, safety, and environmental protection are paramount.

Tiger Valve Company (TVC) is a trunnion-mounted ball valve manufacturer.  

TVC Trunnion-Mounted Ball Valves (TMBV) meet the latest API, ISO, and ASME standards—manufactured using best-in-class materials and technologies. The result is the highest-quality and most competitively-priced trunnion-mounted ball valve available. 

All TVC TMBV address all of the safety, quality, and design issues important for ensuring consistent field performance and environmental protection. They provide superior performance in various applications, including oil, gas, and other liquids pipelines, tank farms, meter stations, chemical processing plants, and refineries.

The MASCOT GFlo Globe Control Valve

MASCOT GFlo Globe Control Valve

Superior performance in liquids and gaseous services is the hallmark of the GFlo Globe Control Valve by MASCOT. Easy, quick, and economical maintenance makes the GFlo Globe Control Valve more user-friendly. The spring cylinder actuated GFlo imparts stiffness and maintains very high precision in positioning. A strong response, repeatability, and high-speed controlled movement are the characteristics absent in diaphragm operated control valves. GFlo has the thrust capability to shutoff against higher fluid pressures,  up to 150 Psi / 10.30 Bar air supply.

Valve closure is dependent on springs in most diaphragm actuators. The unique design of GFlo enables it to combine the spring force, fluid pressure, and supply air pressure to achieve a tight shutoff. A self-aligning seat ring adds to and further improves the shutoff capability.

Galling at the cage is the culprit in many common maintenance issues with globe valves because of the close metal-to-metal contact between plug & cage. The GFlo has two top heavy-duty stem guides. Interference between the plug and seat retainer does not exist in GFlo. Easy and quick maintenance is due to the clamped-in seat and top entry trim.
