Pneumatic Control Valve
ZXP/ZDLP/ZAZP series pneumatic/motorized single seat control valve structure is top guiding.The advantage as below: 1.Compact structure 2.Small volume 3.Lighter 4.Sensitive action 5.S type Flow channel, low pressure drop loss, large circulation capacity,flow characteristic precise,easy...
Pneumatic pressure control valve is the most important actuator product in. production process control system. This series product ZXP/ZDLP/ZAZP type pneumatic small type single-seat control valve and ZJHM type pneumatic small sleeve valve is one of the universal product available for users to choose, it is suitable for various fluid media and process conditions of the process control system.
ZJHP type pneumatic single-seat control valve is consist of ZHA (B) pneumatic Multiple-springs diaphragm mechanism actuator and low flow resistance Straight-through single-seat valve.
ZJHM type pneumatic sleeve control valve is consist of ZHA (B) pneumatic Multiple-springs diaphragm mechanism actuator and low flow resistance Straight-through sleeve valve.
The outer pneumatic pressure signal transmit into membrane chamber, the pressure acts on the diaphragm and produce thrust, this force compress onto springs and makes a putter move and drive the valve stem which lead valve core ON or OFF, until the thrust and spring set force get balance and stable on a position. Above all, the valve core displacement is in proportion to the input pressure signal, so also called as pressure control valves.
Classify Pneumatic spring diaphragm actuator according to action mode, can be divided into positive action and reaction action two kinds. When the signal pressure increase, the push rod move out the membrane chamber, is positive action model ZHA; when signal pressure increase, the push rod back into the membrane chamber, is reaction type, model is ZHB.
Classify the pneumatic control valve with switch mode, have air-to-close type and air-to-open two types. Air-to-close type is made of positive action actuator and valve. When the input signal pressure change from low limit to high limit, valve move from full open to full closed. Air-to-open valve is made of reverse action actuator and valve. When the input signal pressure change from low limit to high limit, valve move from full closed to full open.
