## Summary description

Comap PWE2429 is a straight check valve with 3/4" connection designed for hydraulic and heating systems. It features an adjustable setting and an integrated flow shut-off to control backflow and isolate sections for maintenance. Suitable for use in radiators, boiler circuits and general plumbing where controllable non-return function is required.

## Long description

Comap PWE2429 is a straight check valve with a 3/4 inch connection intended for hydraulic and heating installations. The valve combines a non-return function with an adjustable setting and an integrated flow shut-off, allowing controlled prevention of backflow and isolation of pipe sections for maintenance. It is designed for inline mounting and compatible with typical radiator and boiler circuits as well as general plumbing applications requiring a controllable check valve.
Advantages
The valve provides adjustable backflow prevention, enabling fine tuning of cracking pressure to match system requirements. The integrated flow shut-off allows quick isolation without additional fittings, simplifying maintenance and replacement. Its straight inline design supports space-efficient installation and reduces hydraulic resistance in typical domestic and light-commercial circuits.
Suitable for
Radiator circuits in central heating systems
Boiler return lines and heat generator protection
Domestic and light-commercial plumbing where non-return function with isolation is needed
When it may not be suitable
This straight check valve is intended for hydraulic and heating systems with compatible 3/4 inch connections; it may not be suitable for systems requiring threaded sizes or face-to-face dimensions different from the valve’s design. Systems that demand full-port, high-flow-rate non-return valves or specialized sanitary check valves with additional certifications may require a different product.
Key specifications
Connection size: 3/4 inch
Function: non-return (check) valve with adjustable cracking setting
Feature: integrated flow shut-off for isolation
Design: straight/inline
Typical applications: heating and hydraulic circuits, radiator and boiler return lines
How to use
Install the Comap straight check valve inline in the return or supply piping with the correct flow direction indicated by the valve body. Set the adjustable cracking pressure according to system requirements to ensure reliable non-return performance without undesired pressure loss. Use the integrated shut-off to isolate the valve or downstream section during maintenance, repair, or replacement. Follow standard installation practices: ensure clean pipe ends, apply appropriate thread sealing, and perform leak and function tests after commissioning.
What to consider before purchase
Verify the 3/4 inch connection matches your system fittings and thread type.
Confirm the valve’s cracking pressure adjustment range suits your hydraulic scheme.
Check space and orientation requirements for inline straight installation.
Ensure compatibility with the system’s working pressure and medium (water, glycol mixes if applicable).
Usage recommendations
For reliable operation, set the cracking pressure to the minimum value that prevents backflow under normal conditions and periodically cycle the shut-off to avoid seizing. During winter operation with glycol mixtures, verify materials compatibility and flush the line according to system maintenance schedules.
