Stainless steel ammonia shut-off valve

Stainless steel ammonia shut-off valve belongs to the forced sealing type valve, so when the valve is closed, appropriate pressure must be applied to the valve disc to force the sealing surface not to leak. The packing material is made of polytetrafluoroethylene, which has reliable sealing and material leakage. The sealing auxiliary material adopts polytetrafluoroethylene or nylon for the valve body material, which is a soft seal and reliable sealing. This valve is suitable for liquid ammonia storage tanks, liquefied petroleum gas pipeline systems, as an opening and closing device, and also applicable to other pipelines with temperatures ≤ 80 ℃.

Model: AWJ45F-25C J41F-25C J41B-25C AJ41F-25C

Introduction to Stainless Steel Ammonia Gas Stop Valve:

It is a manually operated shut-off valve. As ammonia is a toxic medium, it is required that the packing seal and valve seat seal must achieve zero leakage. Ammonia reacts with copper and aluminum metals, so components of ammonia shut-off valves cannot be used.

Technical Specifications:

Valve body material: WCB CF8 CM8M

Valve stem: er13304316

Packing: PTFE

Valve seat: PTFE

Central seal: metal graphite

Structural form: concealed stem/self sealing (function: there is a strong spring inside, which exerts pressure when the packing wears out)/reverse sealing (function: the valve should be kept fully open to prevent pressure from impacting the stem packing)

Flange: convex surface, concave surface, convex surface

Media used: liquid ammonia, ammonia, synthetic ammonia

Operating temperature: -29 ℃~80 ℃ (soft seal), -29 ℃~300 ℃ (hard seal)

Application pressure: 1.6MPa, 2.5MPa, 4.0MPa, 6.4MPa, 10MPa
