Non-rising gate valve Introduction
Resilient seated gate valves made of speclal rubber elastlcly full wrap-plece valve structure, and the general absence of gate leakage or rust compared to other phenomena. Overcome their common seal bad, elastic fatigue, wear rubber aging and Sealing ruts and other defects、 Produced by ths elastic saeling full compensation of small quantities of deformation to achieve a good sealing effect. It can be widely used in water supply, petrochemical, metallurgy, shipbuilding, food, pharmaceuticals and energy systems and other fluid line is used as a regulator and shut-off devices.
Non-rising gate valve Features
1. The overall package of plastic: the spool and the latest high-performance rubber vulcanization technology overall coating. laminating are tight. accurate geometry, rellable sealing and long service life.
2. Light weight: body ductile iron material, gate valve to reducs weight than tha average 25%, easy installation and maintenance; gate valve maximum opening helght is generally low 60mm ~ 280mm, can be Installed where space is llmited.
3. Flat style seat: The bottom of the pipe the same flat style seat design, does not produce debris accumulation, flow channel unimpeded and reliable sealing.
4. Corrosion resistance: the valve cavity using non-toxic epoxy powder coating, inner parts mining copper alloy and stainless steel to prevent corrosion and rust.
5. The three 'O' seal: the use of the stem seal O-ring seals, friction is small, lightweight and watertight gwitch.
