Z11Y/Z61Y pressure sealing forged steel gate valve

Product introduction:
The pressure from tight type forged steel gate valve with pressure self-tightening type valve cover, according to this design form design of the valve, the valve body and valve cover are in threaded connection, pressure from the seal ring seal.

Application range:
Forged steel gate valve is applicable to Class150 ~ 2500, -29 ~ 425℃temperature ( carbon ) or -29 ~ 500℃( stainless steel ) for small diameter pipeline, used to cut off or connect the line of medium, use different materials, can be separately applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media.

Pressure seal forged steel gate valve adopts the following structure:
Full diameter forged steel gate valve or reduced diameter forged steel gate valve
The lever bracket type ( OS&Y )
Self-centering clamp pressure sleeve type
Threaded connection pressure from the tight bonnet
Integral seal seat
The socket end with ASME B16.11
Threaded ends ( NPT ) with ANSI/ASME B1.20.1

1 forged steel valves with pressure seal, valve pipe ends are connected by welding.
The 2 valve seat, valve sealing surface of valve using cobalt-based alloy plasma spray welding, wear resistance, anti-abrasion performance.
3 stem through the corrosion resistance of nitriding, good resistance to corrosion and scratch resistance.
