Product Description

1. Brief introduction

It is a kind of knife-shaped Slurry Valve, its rubber seal ring could be replaced. Its sealing theory is that disc and rubber seal ring closely contact with each Other to achieve it sealing ability. The prominent feature of the structure is: rubber seal ring is wrap-rounded in the stepped grooves on the valve seat and the seal ring is counter-locked by metal gland and thus these seal rings will not fall off during the open, close and seal process between seal ring and disc.additionally, if seal ring is broken, we could take out the metal gland and replace the broken seal ring by a new one and the service efficiency of valve will be improved greatly. In view of the above, it is a kind of high performance product, economic and efficient.
