Resilient Seated NRS Gate Valve
Features
1. The valve is designed as to our newest notation, which has simple construction and can be maintained easily.
2. The valve is of low torque and high pressure, the pressure can reach PN40 under one third of the standard torque.
3. When the valve is fully opened, the upper sealing parts can be replaced under water supply.
4. The valve is of straight channel, when the valve is fully opened, the disc will leave the channel totally, so there is no dirt left and the flow resistance is much smaller.
5. Outside and inside surface of the valve is coated with high quality of epoxy powder, so the painting is more complete and even, and can be used on drinking, food and pharmacy etc.
