High temperature steel flange spool U41H-10C

Changzhou and Shanghai Valve Co., Ltd. mainly produces fly piston valve] [high temperature, is the famous "spool" manufacturers, for our customers to create the appearance of fine, reasonably priced, guarantee high-quality high-temperature piston valve []; I Companies continue to use new materials, new technology to protect U41SM high temperature piston valve product suitability for working conditions, long service life, high temperature piston valve structure and characteristics: high temperature piston valve is a valve body, valve cover, stem the plunger hole frame, dense rings, hand wheels and other parts (see figure). In the valve between the plunger and the sealing ring with an interference fit, by adjusting the gland flange bolts, the sealing ring compression products and lateral force generated in the cylindrical bore surface of the valve body and the plunger seal, thus ensuring the valve sealing, to prevent internal leakage, the valve opening moments while small, can achieve rapid opening and closing of the valve. Due to high temperature piston valve seal ring with strong resilience, high abrasion resistance, non-toxic new sealing material, having to withstand long-term high temperature and high pressure without losing elasticity, reliable sealing performance and durability.
