Why Choose Our Gate Valves?
Good Casting Quality
Every Bosseal valve casting will be inspected under MSS SP-55 with strict control of defects like gas porosity, cracks, and shrink.
Great Seal with Long Working Life
The flexible wedge can compensate for seat surface distortion and body deformation, seating surface is with enough wearing travel and with hard facing (CoCrA) upon request.
Low Flow Resistance
The straight and standard bore allows more fluid passing and low flow resistance at the full opening position.
Easy and Lockable Operation
The reasonable torque of gland nuts, long thread stem and good stem nuts make the valve low operation torque and easy to open/close. Handwheel/gear is with lockable structure.
What is a gate valve?
The gate valve is a multi-turn valve that is installed in the pipeline as an isolation valve for full open and close service.
The valve is operated by a threaded stem forcing the gate to the two seats and blocking the fluid. The seats are normally metal with hard facing(stellite CoCrW or SS Overlay) to ensure a long working life. It can also be a soft seat for specified services like water.

Features of Gate Valves
Compared with another shut-off valve, it needs smaller installation space. And due to the multiturn design, the slow operation can also avoid water hammer effects. It’s often used when needing low-pressure drop and free bore.
