Product Details
API 602 forged steel valve, small size forging steel check valve,
NPT, SW ends
Standard Features:
Forged steel check valve, bolted bonnet, threaded or Socket weld
ends, Full or Reduced bore, Designed to API-602.
Design characteristics :
- The valve seat and the slide sealing surface are build-up welded
with hard alloy to improve the scouring resistance and extend the
service life of the valve
- SS+ graphite or metallic seal or pressure self-sealing is adopted
between valve body and bonnet for reliable sealing.
- Rising stem structure, making the valve switch position be clear at
a glance.
- The valve stem thread will not come into contact with the medium,
so the corrosion of medium to the thread is reduced.
- Small switching moment, reliable sealing.
- Small flow resistance, high flow capacity and good flow
characteristics.
