EPDM Sealing Gate Valve

DIN3352 F5 Gate Valve

This gate valve can only be fully opened or fully closed, cannot be adjusted or throttled.

Resilient seated gate valve is devided into 2 types: Rising stem type and Non-rising stem.

The openning and closing part of Resilient seated gate valve is the bonnet, and its movement direction of the bonnet is perpendicular to the fluid direction.

The bottom of this resilient seated gate valve adopts the same flat-bottom design as the water pipe which makes the fluid is unimpeded and is not easily to cause debris to accumulate.

High-quality rubber is used for integral internal and external coated when produce gate valve, first-class rubber vulcanization technology ensures accurate Geometric size, also will not easy to fall off which have good elastic memory.

Valve body adopts precision casting and powder epoxy resin coating to prevent corrosion and rust of the valve body.

Flat Bottom Sealing Design

Traditional gate valves are often deposited in the bottom grooves after washing pipes, such as stones, wood blocks, cement, paper scraps, sundries, etc. It is easy to cause the leakage phenomenon which can not be closed tightly. The bottom of the soft sealing gate valve is designed with the same flat bottom as the water pipe, which is not easy to cause debris deposition and make the fluid unobstructed

Overall Rubber Lined

This gate valve bonnet is lined by EPDM rubber by vulcanized production method which ensure the accurate geometric dimensions, it is firmly connected for rubber and ductile iron material and it will not be esaliy falling off which has good elastic memory of rubber.

Corrosion Resistance

The valve body adopts epoxy spray to prevent any rusty or corrorsion on it, additionally, it is can be used for sewage systems. ?

Not Easily Broken

Traditional iron gate valve usually can be broken when hits or collision or overlap, this type soft sealing gate valve has seldom such situation as its body material changes to be GGG50

Use for drink water system

It is coated with non-toxic epoxy resin for this gate valve inside body ,the inner and outer surface of it are completely covered with rubber which can prevent any rusty ?water or corrosion.

MF Valve Co. got WRAS Certificate of this gate valve which can be using for drinking water system.

?

1. Clean the valve body cavity and sealing surface before install this gate valve, to avoid any dirt attachment.
2. It must be parallel between gate valve and flanges when installation, please remember to tight bolts well.
3. Make the lubricant on the valve stem frequently when use gate valve, this is better to protect valve rotation and corrosion.
4. The bonnet of this gate valve needs be fully open or closed , it not allows to be partially opening or closing when installation.
5. The gate valve bonnet should be in a vertical position when installed on a horizontal pipe. The handwheel can be in any direction, but it's better to be in the upper part.

We recommend Rising stem gate valve for you if you need install it to the position where be higher than the ground, as this rising stem can shows clearly when valve opens or closes.
