Rubber Flap Stainless Steel Swing Check Valve For Water And Oil Vapor

Guaranteed performance

General:

o The swing check valve is applied to the horizontal pipelines or the vertical pipelines in which medium flow run supwards,The backwards flowing is effectively stopped. Disk of the damping and swing check valve is connected with two level of damp oil which is outside the valve. Lt can control the speed and time of valve closing, insures the safety of device.The valve could be widely used in water-supply and drain system.

Professional design:

o To keep medium pure, the disc is covered by rubber.The reinforced tyre fabrics and soft metal fabrics is inserted to increase the operation life of disc.

O The disk that is relative to vertical is a certain degree when

it is closed.The hole of the body and the disk are ellipse.The channel of the valve is direct. The closing angel is smaller.These insure the safely of device when the medium is flowing backwards. The cavity space enable the obtaining of maximum area of flow section.

o The reasonable open limit and cavity space enable the obtaining of maximum area of flow section. The flow resistance is comparably small and the valve parameter Cv is improved

0 This disk sprayed with stainless steel and vulcanized with rubbers have double sealing surfaces. lt's credibility for seal completely of valve.This is one kind of most advanced seal currently in the world,

O The valve is opened and closed by the damping oil. The oil device adopts two level and controlled of damp. When the disk is far from the sealing surface, the oil flow through double pipes, closing fast; When near the sealing surface,the oil flow through single pipe, closing slow. It can avoid the impact of the disk to the sealing surface , increase the durability of valve.

O The design of oil is reasonable, Not equality inside the wall keep the . O" seal ring moving back and forth in the oil urncompletely The speed of opening and closing valve can be controlled by regulate the needle valve.

Excellent corrosion characteristics:

o Internal and external of body. cover. disk. connect stem,joystick and body of oil urn epoxy resin coating

Reliable hygiene principles:

o epoxy resin and rubber comply with hygiene standard GB/T17219-1998.

o Suitable application:

O Water-supply system ,drain system and heating system

o Potable water supply, industrial fields.
