The extension stem gate valve is for the convenience of customers to operate the valve at the bottom of the well on the ground, The long stem works well. The resilient seated gate valves is made of speclal rubber elastlcly full wrap-plece valve structure, and the general absence of gate leakage or rust compared to other phenomena. Resilient Seated Gate Valve Body: Ductile Iron,
Resilient Seated Gate Valve Seal: Ductile Iron+EPDM (Resilient Seated)
Resilient Seated Gate Valve Stem: Stainless Steel 304, the medium of the soft seal gate valve is Water, Waste Water, Air. the working temperature of the resilient Seated Gate Valve is from -20 to 120℃. No restrication torwards the fluid’s direction and no turbulence to the flow, it will also not reduce the pressureEpoxy painted inside is anti-corrosion as well as avoiding the secondday pollution to the fluid. The wedge is coated with EPDM, the EPDM proportion can reach 50%，steable and good resilientEach product will be carried out appearance, material, air tightness, pressure and shell testing before leaving the factory ; unqualified products are resolutely not allowed to leave the factory.
It can be widely used in water supply, petrochemical, metallurgy, shipbuilding, food, pharmaceuticals and energy systems and other fluid line is used as a regulator and shut-off devices.( It is used as a cutoff and adjusting equipment for the various water supply and drainage pepeline in building ,chemial ,medicine,textile,ship and other industries.) Zhongfa valve can offer OEM &ODM gate valves and parts in China.Zhongfa valve's philosophy is to seek for high quality products with optimal service with the most ecmonical price. All valve product are test two times before shipping to ensure the quality of the product. Welcome to visit our factories. We will show the Craftsmanship of the valves.
