Resilent Seated NRS Gate Valve, Ductile iron, Fusion Bonded Epoxy Coated

Our company is specialist in design and production of high quality water valve, and has grown to become one of the leading manufacturers for fluid control valve. We design and manufacture a wide range of fluid valve,, such as float control valve, trunnion ball valve, water pressure reducing valve, rotary airlock valve, sanitary butterfly valve, hydraulic check valve,sewage air release valve, etc. Our constant technical innovation combined with stringent quality control systems has enabled us to deliver high performance and outstanding value in industrial applications.

Resilient seated gate valve is a soft seated wedge with fully encapsulated with rubber. The valve is designed by 3D software solidworks for light operating and weight. The FBE coating provides no corrosion for both interior and exterior. A good resilient memory & long service life by rubber wedge. 

Newly advanced design, less operation torgue & abrasion resistance.

Features:

•  Body & bonnet are made of high grade ductile Iron GJS500-7

   
•  Disc is designed with an abrasion resistant nylon guide which can help less opening or closing torgue and smooth during operation.

   1. EPDM fully vulcanized

   2. WRAS approved 

•  Forged stem provide stronger stem operation and less moving parts.

   1. Stainless Steel 420 / Stainless Steel 431 / Stainless 304/ Stainless Steel 316 are available.

   2. Platform provide better strength

•  Ductile Iron inside the wedge is covered by WRAS Approved EPDM which is suitalbe for drinking water.

•  High-tech rubber curing with precise geometry dimensions, more resilient & strong adhesive to ductile casting.

•  The 4 O-ring stem seals are designed to prevent stem leakage. and provide replacement of the O-ring without disassambling of valve from mainline pipes.

•  Both inside & outside are coated with epoxy powder.

•  Manufacturing standard meets BS EN 1074-1, EN1074-2, BS 5163, BS EN 1171.

•  F/F (Face to Face) meets the following standard: BS EN558-1.

•  Bolts are protected by silicon glue.
