Resilient Seated OS&Y Gate Valve
Features
1. The resilient seated OS&Y gate valve is designed as one of our newest products, with a simple construction and easy to maintain characteristics.
2. The gate valve has a low torque and a high pressure. The pressure can reach PN40 under 1/3 of a standard torque.
3. When the valve is fully opened, the upper sealing parts can be replaced under a water supply.
4. The valve is a straight channel. When the valve is fully open, the disc will completely leave the channel, so that there is no dirt left behind, and the flow resistance is decreased.
5. The outer and inner surface of the valve is coated in a high quality epoxy powder, so that the paint coating is even and complete, making the gate valve safe for use in the beverage, food and pharmaceutical industries.
