DN50 PN10 Ductile Iron Cast Steel Stainless Steel No Rise Stem Manual Gate Valve For Water Conservancy

Product Introduction

The gate valve is a kind of valve that opens and closes through the ram, and its working principle is based on the function of the ram moving vertically along the axis of the valve seat to achieve the function of full opening or closing, and cannot be used for regulation and throttling.

Gate valve structure and working principle

A gate valve is mainly composed of a valve body, a sealing ring and a valve stem. When the stem rotates or moves up and down, the ram opens or closes to control the fluid. The sealing method usually adopts face seal or bimetal seal, which has the characteristics of good sealing and corrosion resistance.

Types and characteristics of gate valves

Gate valves are divided into two types: wedge type and parallel type according to the different structure of the gate. The gate plate of the wedge gate valve is wedge-shaped, and the wedge action is used to achieve sealing; The sealing surface of the parallel gate valve is parallel and perpendicular to the channel centerline.

The advantages of gate valves include small flow resistance, labor-saving opening and closing, compact structure, wide range of application, etc.
