Stainless Steel Float Ball valve

Stainless Steel Float Ball valve

Stainless steel float ball valve is a valve, made of stainless steel, which is regulated by the position of a free-floating ball that moves in response to fluid or mechanical pressure.Stainless steel float ball valve contains: one-piece uni-body design, two-piece split body design, and forged steel split body design. Wide range of body and trim material is available for service working temperature from -196 to 250, size from 1/2 to10 and pressure rating from ANSI class 150 to 1500. The main material for the stainless steel float ball valve is stainless steel. BSPP is an available end connection. Viton, Nitrile and EPDM are available for the seal options. As for the float options, there are different sizes such as 90, 110, 160, 200 and 300mm diameter. Cylindrical and Flat type floats are available for the stainless steel ball valve. Stainless steel float ball valves are perfect for the aggressive water applications, increased resistance to corrosion and chemicals, boiler feed water systems, car wash, food service and sanitary applications and many other agricultural and industrial uses.

The stainless steel float ball valve has the following features. Firstly, stainless steel float ball valve’s fire safe is designed in accordance with API 607 & API SPEC 6FA. Secondly, the stem of the stainless steel float ball valve is designed with integral T-type shoulder to provide blow-out proof effectively. It is internally inserted as the backseat function to assure stem sealing safety at all pressures. Antistatic devices between ball & stem and stem & body are assembled by a spring & a stainless steel ball, which ensure all metal valve parts are grounding. Thirdly, the stainless steel float ball valve has the low emission packing. The cone packing is made of expanding graphite in die-formed rings and has features of heat resistance, less stress relaxation and low creep. With this special structure, it allows for a low-friction on rotary & rising stem valve, therefore providing the stabilized sealing performance for long cycle life. For low temperature service, the standard V shape PTFE packing rings are used for low emissions control.
