About Our Valves

 

We design and manufacture a broad range of O&G valves for the upstream, midstream and downstream markets including, ball, gate, check, globe, butterfly and plug valves. Our extensive product offering encompasses a wide array of valve types, sizes, pressures, materials end connections and further detail specifications to satisfy the unique valve needs of our customers. 

 

Through Conduit Gate Valve

 

Hi-Alloy Valve's Through Conduit Gate Valves are available in Expanding Gate, Slab Gate and Wedge Gate design and manufactured in accordance to API 6D standards.

 

Our Slab Gate designs are simple but efficient in performance. Our designs utilize spring loaded floating seats which are pressured energized, moving the upstream seat in contact with the gate that brings about a tight and complete seal on both the upstream and downstream.

 

Through Conduit Gate Valve GT02 Expanding Gate

 

Expanding Gate design is versatile in that it provides a mechanical seal between the seats and the gate ensuring valve integrity at both high and low line pressure. The Expanding Gate Valve does not rely on line pressure to seal and is recommended for applications when a tight mechanical seal is required.

 

Trunnion Mounted Ball Valve

 

3-Piece Body Trunnion Mounted Ball Valve

 

Hi-Alloy Valve's ball valves are trunnion mounted supported and available in sizes 2" to 48", ANSI class rating 150 to 900 lb.  All meet the fire safe requirement of BS 6755 and API 6FA. All BS series ball valves are featured with trunnion mounted ball and independent floating spring loaded seats which provide bubble-tight shut off and low operating torques, even at low different pressure.  Double seating O-rings or a combination of an O-ring and gasket in stem making this series of ball valve suitable for both above ground and underground service.

 

HAV's Ball Valve designs include 2 piece & 3 piece, trunnion and floating in carbon and alloy steel and are manufactured in accordance to API 6D standards.

 

HAV's Ball Valve Trunnion Mounted supported and available in sizes 1/2" to 48", ANSI class rating 150 to 2500 lb. All meet the fire safe requirement of BS 6755 and API 6FA. All BS series ball valves are featured with trunnion mounted ball and independent floating spring loaded seats which provide bubble-tight shut off and low operating torques, even at low different pressure. Double seating O-rings or a combination of an O-ring and gasket in stem making this series of ball valve suitable for both above ground and underground service.

 

Full Opening Check Valve

 

Hi-Alloy Valve's Full Opening Check Valves are designed in accordance with API 6D and is available in class rating from 150 to 900 lb, in sizes 2" to 48". With full opening design, this series of check valves can be capable for pig ball cleaning service. To prevent potential water hammer damage caused by disc closing, a dashpot device can be assembled to control the disc closing time. The function of a check valve is to prevent reversal of flow automatically and promptly and this type of valves are usually supplemented by gate, ball or other valves.

 

Plug Valve

 

• Self lubrication of PTFE, which prevents oil stain carried with injected oil.

• Soft surface bring with better seal.

• Low torque.

• Anti-static construction.

• With all kinds of actuators above 4".

• DN(SYMBOL) NPT end or threaded end.

 

Usage:  this plug valve is suitable for the medium of No.3 HWS04 of the -30~180(degrees) and other corruption pipeline to be used as open & shutdown equipment.
