Description:
Brief introduction:
The series of gate valves include cast steel gate valve and forged steel gate valve. They are
 designed and manufactured according to ANSI B16.34. With solid wedge and flexible wedge, 
so it can be used for different pressures. Gate valves have back seal. Back seal of forged-steel gate valve is weld with stainless steel. So it has perfect sealing. Its maintenance is 
convenient. Widely used in petroleum,chemistry,water treatment industries.
Applications:
Features:
 
- \"H\" type wedge:
Gate valve has \"H\" type , flexible single wedge. It can compensate the distortion of body. So it
 has reliable sealing and prevent wedge against difficult operation because of overload. It is 
suitable to steam and other high temperature medium.
 
- Full port design:
Gate valve has full port. So it is convenient to clear pipeline.  - Changeable seat:
Seat and body is connected with thread. So seat can be dismantled and changed, It is convenient
 to maintenance.
 
- Precise design:
Design the body and bonnet according to precise calculation. body and bonnet have high strength
 , rigid and flow ability
