Check Valves and Strainers Dual-plate Check Valve Installation SERIE 2000 dual-plate check valves are designed for quick and straightforward installation between standard flanges: - Low weight and compact design - Installation without additional piping support - Can be installed in horizontal or vertical pipes - Easy to install without special tools - No maintenance required Design of SERIE 2000 Class 300 dual-plate check valve: - Standard: flat-face flanges (FF), flange faces machined to "stock finish" Ra 6.3 to 12.5 (KSB code 1B) - Optional: flat-face flanges (FF), flange faces machined to "smooth finish" Ra 3.2 to 6.3 (KSB code 1A) - On request: raised-face flanges (RF)

Optimum installation (horizontal pipe)

In a horizontal pipe, the dual-plate check valve must be installed with the hinge pin in a vertical position.

CORRECT

INCORRECT

Installation in vertical pipe

When installed in a vertical pipe, the dual-plate check valve will only function reliably if fluid flow is upwards. (Please contact us if flow direction is reversed, i.e. downwards).

Check Valves and Strainers Dual-plate Check Valve

System configuration

Depending on the system configuration, minimum distances must be observed between the dual-plate check valve and elbows or piping tees. The drawings below show a horizontal pipe (viewed from above) in which the dual-plate check valve is installed with the hinge pin in a vertical position. The minimum distance for a dual-plate check valve installed downstream of a turbulence-causing element (elbow, pump, valve, etc.) is 5 DN. If a turbulence-causing element is installed downstream of the dual-plate check valve, any special instructions regarding the respective element or a minimum distance of 2 DN must be observed.
