Self-reliance type pressure pneumatic regulator is the main type and function

Self-reliance type pneumatic pressure regulator ( Self-reliance type pressure control valve) Without additional energy, use energy modulated medium itself as the source of power, introducing device, control valve core position change at the ends of the bending differential pressure and flow, make the valve before ( Or after valve) Pressure stability. Action sensitive, good sealing, the advantages of small pressure set point wave power, self-reliance type pressure control valve is widely used in gas, liquid and steam medium pressure regulated or pressure regulator, automatic control. Self-reliance type pressure pneumatic regulator is the main type ZZY, ZZV, ZZYPII, ZZW, ZZD, ZZFX, etc. Type ZZY direct effect of self-reliance type pressure pneumatic control valve. ZZV type direct effect of self-reliance decline pressure pneumatic control valve. ZZC direct effect of self-reliance type differential pressure pneumatic control valve. ZZYPII command unit operation model of self-reliance type pressure pneumatic control valve. ZZW self-reliance type pneumatic control valve temperature. ZZD nitrogen sealed type control device. ZZFX type explosion-proof fire breathing valve.
