Control Type Single Seat Regulation Valve
Product Introduction
Single seat control valve adopts top guide actuator, flow channel of the body is S streamlined. It has the following characteristics: small pressure drop loss, large flow, wide adjustable range, high accuracy of flow characteristic curve, large guide area of the spool, good shock resistance. The valve uses multi - spring type film actuator with compact structure and large output force. It can be used to control fluids of different pressures and temperatures.
