Simple understanding Angle of pneumatic diaphragm type high pressure pneumatic control valve

Pneumatic diaphragm Angle and pressure pneumatic - valve by pneumatic diaphragm spring more actuators and Angle of high pressure valve. It USES the boundary type seat structure, the seat is easy to change, sealed performance is good. DN≤ 25 seats, valve core head adopts 6 yc1 carbide, DN≥ 32 valve core adopts surfacing welding, tungsten cobalt alloy, cavitation resistance, resistance to washing and other advantages, greatly improve the service life. Pneumatic diaphragm Angle and pressure pneumatic - valve widely used in all kinds of chemical industry, oil refining and other industries, especially suitable for synthetic ammonia, urea, medium high pressure and high pressure difference on the industrial adjustment. Body type is type Angle single-seat valve casting; Nominal diameter 6, 10, 15, 25, 32, 40, 50, 65, 80, 100 mm; Nominal pressure for PN22, 32 mpa; Standard for H12 - flange 67; Materials have forged steel, cast stainless steel ( 1Cr18Ni9Ti、1Cr18Ni12Mo2Ti） , 316 l, etc; Carries on the valve type, its temperature - 40 ~ + 230 ℃, the cooling type, the environment temperature of + 230 ~ + 450 ℃; Gland is the bolt clamp type; Packing available v-shaped braided packing ptfe packing, asbestos, graphite packing.
