Product description
Electric three-piece ball valve with integrated structure, matching with HL Electric actuator and can be run with input (4-20mA. DC, 0-10VDC or 1-5V)signals or single-phase power. With the function of small volume, flow capacity, high regulation precision, good sealing, and light weight, etc. The valve is widely used in food, environmental protection, light industry, petroleum, paper, chemicals, teaching and research equipment, and electric power industries of industrial automation control systems.
Product Features
Thread connecting and welded connection ball valve can be divided into the overall style(a style), two stage and three stages. Body cast adopt the advanced technology from Taiwan, with reasonable structure and beautiful shape. The elastic sealing structure make the seat reliable and easy to start. Valve stem seal downloading using inverted structure, The lower-loading Stem with backward sealing construction not only prevents the handle form backing-out but also ensures the reliability of the scaling part of the handle. There
Is butt weld(BW) socket welding (SW) connection of the 2-piece, 3-piece ball valve, and can match with the international standard ISO platform and locking devices. 90° Switch positioning can be set, preventing accidental operating as necessary.
