HYDRAULIC CONTROL VALVE GENERAL INTRODUCTION SHANGHAI SHINJO PUMP & VALVE CO., LTD.

PRODUCT INTRODUCTION Hydraulic control valve is introduced from Taiwan in late 1990s, which is applicable to the water irrigation system in some agricultural countries firstly, produced largely in European countries like Israel, Holland, Demark, and then America, Canada and Asian countries, and even it is applicable widely to many other fields except introduced from Taiwan in late 1990s, which is applicable to the water irrigation system. Our hydraulic control valve has outstanding achievement in many domestic & abroad building, fire fighting, municipal, electrical power, pipe networks...

Flexible Gasket and NBR Sealing Ring The bonnet and body inside groove is located by piston cylinder excircle, making sure the bonnet, body and indicator stem are concentric, and the disc move freely. Thereby, it increase the main valve sensitivity, which makes the piston type hydraulic control valve can work reliably even though the flow and pressure vary a little. In order to achieve the joint between body, bonnet and piston cylinder has no leakage, the joint between piston and bonnet adopts flexible gasket, while the joint between piston and body adopts NBR sealing ring. Two Guide...

Guide Hole Makes it Move More Smoothly In order to make the hydraulic control vavle up and down valve cavity have pressure difference, the piston must be bigger than disc, in this case that the piston of large sized valve will be very big, as a result that its moving will be not stable. In order to solve this problem, we design the guide hole at the end of piston cylinder in order to increase the disc damping properly, and then makes the disc move more smoothly, increase the valve reliability, as a result that reduce the breakdown happened. The guide hole is evenly distributed at the end of...
