Description

RK Gate Valves, which are ideal for bi-directional, low friction flow and 100% tight shut-off. Due to the flow characteristics of the wedge to seat design, Gate Valves are operated in the full close or full open position.

Wedge Gate Valves for high pressure and/or high temperature services. It is important to make the material selection according to the fluid corrosion.

Big size and/or different/special material are available upon request.

A disc housed in the gate valve’s body slides up and down at right angles to the direction of flow in the pipe, closing or opening the valve. Flow is blocked by using the wedge-lock effect of the valve’s disc.

Features

• wedge and stem technology ensures smooth functionality with outstanding low torque values
• New guiding system for the wedge with male composite sliding skate in order to easily achieve the 2500 cycles endurance test .
• clear way and straight bore design allow a free path without restriction of the fluid.
• Wedge design with increased thickness of the elastomer at the sealing areas to improve tightness.
