ZHJ Type Angle Control Valve (Pneumatic / Electric) 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.
