WINDMILL steel gate valve

For carbon steel gate valve, the seat is usually forged steel. The sealing surface of the seat is spray welded with hard alloy specified by the customer, Renewable threaded seat is used for NPS 10 gate valves, and welded on seat can be also optional if being requested by the customer, Welded on seat is used for NPS 10 carbon steel gate valves. For Stainless steel gate valve, integral seal is usually adopted, or to weld hard alloy directly integrally.

Non Rising Stem Resilient Seated Gate Valve

The gate valves disc is rubber-packed to get excellent sealing effect by the rubber's resilient deformation. Non-rising resilient seated gate valves solve the problem in general gate valve such as leakage, rusting etc. and saves installation space. It is used widely in tap water industry, sewage treatment, shipping construction, petroleum, chemicals, food, pharmacy, textile, electric power,

API 600/BS1414 Gate Valves

The API 600 gate valve is divide into two big types by sealing surface configuration, include wedge-type gate valve and parallel-type gate valve, wedge gate-type valve can be divided into: single-disc gate valve, double-disc gate valve and flexible-disc gate valve; the parallel-type gate valve can be divided into single-disc gate valve and double-disc gate valve. According to location of the thread on the stem, the division can be divided into rising API600 gate valve and non-rising gate valve.
