China Manufacturer Resilient Gate Valves for Drinking Water WRAS certified
What's Resilient Gate Valves ?
Resilient Gate Valves, a design principle that is dominant in preference for use in distribution systems.
Resilient Gate Valvesare very popular for industrial application.
- 1)Perfect sealing:bi-directional bubble sealing.
- 2)Low cost:rubber seat is vulcanised on the wedge,no need for further machining of valve seat.
- 3)Simple structure and Easy maintenance
Main features of NORTECH Resilient Gate Valves
The stem is made of stainless steel by rolling. Integral type,avoiding the use of the brass half rings to reduce stem diameter. the smooth modified ladder type screw is extruded. Global mirror polish,it fits the O rings well, to ensure that the smooth rotation and small torque.
The frame of the wedge is made of ductile iron by the precoated sand moulding,the wedge is covered by EPDM totally.Double seal design,each seal line can work independently
Environmental friendly manufacturing
The inside and outside surface of the valve is coated with sanitary epoxy powder by fusion bonded epoxy(FBE), the average thickness is above 250um. The adhesion of the coating is strong,it won't be destroyed under the impact force test of 3J. Internal parts can meet with the environmental protection requirements,and can be used for the potable water,food and pharmaceutical area directly.The electrostatic powder coating process can promise high adhesion force and strong corrosion resistance
The rubber parts are made of high quality EPDM or NBR, which is in accordance with the drinking water requirements,avoiding the problem of the common rubber which is likely to breed microorganism.The products is not only approved by chinese national quality standards for drinking water related products,but also approved by WRAS in UK and ACS in France.The stem nut is forged and rolled from the national standard brass rod (low content of lead),and no pollution to water.
Easy maintenance
The seal ring can be replaced without cutting off the water,it's easier for the maintenance and reduce the maintenance time as much as possible.Very small friction between the brass bushing and the "O" type seal,it will ensure long life of the seal ring.The max. operating torque is under the control.
