Self-operating regulating valve: 1） For ZZY/ZZC/ZZV series self-operating regulating valves, there is no need for any external power source, used fluid adjusted by own energy to regulate automatically, saving power source, pressure set value can be adjusted free during working, quick-opening flow, flexible operation, good sealing property, stable medium pressure, high regulating precision and low leakage. They are widely used in automatic control of the up-valve or back-valve pressure reduction or stabilization of the mediums such as air, liquid and vapor in various industrial furnace burning systems to control the ratio of two different kinds of gases, or in the leakage proof fuel system of the hydrogen cooling electric generating set, and for the micro-pressure automatic regulation of all kinds of fuel and half-finished petroleum of the industrial furnace burning system, oil tank stocking protective gas and heat treatment protective gas. 2） This series of products includes many type such as ZZY standard(self-operated regulating valve), ZZYP-150 1bBII (self-operated regulating valve with operated director), ZZC(self-operated pressure difference regulating valve) and ZZV( self-operated micro-pressure nitrogen-sealing regulating valve). The PN grade of this series of products are 150,300 and 30, the body DN about 1/2-12 inches, the leakage standard is IV grade or V grade, the flow property is quick opening and sorts of specification are optional. Types： ZZY standard type with pressure regulating range of 15-4000Kpa, and main sorts of single-seat valve, cage valve, double-seat valve and four-way valve ZZYP -150 1bBall type with pressure regulating range of 0.5-100Kpa and main sorts of single-seat valve and double-seat valve ZZV type with pressure regulating range of 0.5-100Kpa Main Material Valve body: WCB, WC6,CF8, CF3, CF8M, CF3M Disc: metal parts: 304,316 Valve rod: 420, 304, 30L, 316, 316L, 630 Soft Sealing parts: PTFE, reinforced rubber Valve seat: 304,304L,316, 316L Valve stem: 304, 304L, 316, 316L Spring: 6Osi2Mn, 304, 50CrVA Diaphargm: butyronitrile, ethylene propylene, oil resistant rubber, silicon rubber, flrorine rubber Membrane:Q235BContact the seller
