Rising Card Slot Soft Seal Ductile Iron Gate Valve 1.6mpa Fire Protection Valves

Introduction

Z81x-16 rising stem grooved soft seal gate valve is widely used in water supply and drainage of fluid transmission pipeline, and in pipeline engineering such as fire fighting, air conditioning, gas, petroleum, chemical industry, water treatment, municipal administration and shipbuilding.

The groove rising stem elastic seat sealing gate valve uses the compensation effect of slight elastic deformation produced by the elastic gate to achieve good sealing effect, and has the remarkable advantages of light switching, sealing, good elastic memory and long service life.

The gate of grooved rising stem elastic seated gate valve moves in a straight line with the valve stem, which is also called rising stem gate valve. Generally, there are trapezoidal threads on the lifting rod. The rotation is changed into linear motion through the nut of the valve and the guide groove on the valve body, that is, the operating torque is changed into operating thrust.

The stem and bonnet of grooved rising stem elastic seated gate valve adopt three & ldquo; O” The sealing design of O-ring sealing ring can reduce the friction resistance when switching, greatly reduce the phenomenon of water leakage and the non-stop medium flow in the pipeline. The sealing ring is replaced. In addition, because the interior of the valve body is coated with epoxy resin, the inner and outer surfaces of the valve plate are covered with rubber without molten iron or corrosion, which can be used for raw drinking
