Swing check valve

Swing Check valves prevent reversal of flow through pipe lines. Most COTECH swing check valves can be installed in horizontal or vertical position (flow upward). They offer low resistance to flow and are particularly suited to low velocity service.

General Description

The Swing Check Valve is a one-piece body, top entry design for reliable operation and extended seat seal life. Top entry construction allows field service and in-line maintenance if necessary.


Design

Valve design to API 6D/ASME B16.34/BS1868.

All valves are available with any international flange standard.


Pigable

COTECH Swing Check Valves are full bore. The full bore to API-6D assures unrestricted and allows pigging and hot tapping.


Low pressure drop

The full opening flow passage and high-pressure recovery of the venturi-shaped body result in very low pressure loss: reduced operating cost of pumps and compressors.


Cost Effective

The COTECH swing check valve’s continuous operation ensures reliable protection. Without the need for an outside power source, the COTECH swing check valve is an inexpensive, low maintenance solution to prevent back flow.


For Standard or Critical Applications

COTECH offers swing check valves with a wide range of convenience, performance and safety options. Full opening designs minimize pressure drop across the valve and permit passage of intelligent pigs, scraper pigs and spheres pigs. For turbulent flow conditions in real service, COTECH can offer you a swing check valve solution to meet the requirement.
