ZJHJ Type Pneumatic Angle Control Valve
specialized in high viscosity medium, easy for crystallization, with suspended particle and 90 degree angle area. Angle type control valve without dead space, so easy rinsing, convenient for maintenance and wide application. It can be applied with single or balanced cage disc, or multi-layer in high pressure difference occasion. It can also applied with multi-spring pneumatic diaphragm actuator or electric actuator, etc.
J: standard angle single seat control valve JF: soft seal angle single seat control valve JM: standard angle sleeve type control valve JT: two layer cage sleeve type control valve JG: radiator angle type control valve JV: bellow seal angle type control valve JD: low temperature angle type control valve
