## Summary description

Straight check valve Comap 429204P (1/2") with adjustable setting and flow shut-off. Designed to prevent backflow while allowing manual adjustment of the valve setting and the option to stop flow completely.

## Long description

Comap 429204P straight check valve (1/2") with adjustable setting and flow shut-off is a compact valve designed to allow one-way flow while offering manual adjustment and full shut-off capability. It prevents reverse flow in heating, plumbing and domestic water systems and simplifies balancing and maintenance by combining a check function with an adjustable seat and an integrated shut-off mechanism.
Advantages
This straight check valve integrates adjustable cracking pressure and a flow shut-off in a single compact unit, reducing the need for additional fittings. The adjustable setting enables fine-tuning of backflow prevention to match system requirements, while the shut-off function allows isolation for servicing without draining the entire circuit. Its straight-through design minimizes pressure drop and ensures stable operation in horizontal or vertical installations where permitted.
Suitable for
 Domestic and commercial heating circuits requiring controlled one-way flow
 Plumbing systems to prevent backflow into supply lines
 Hydronic balancing and zone isolation during maintenance
 Applications where manual adjustment of cracking pressure is needed
Key specifications
 Connection size: 1/2" (straight inline connection)
 Function: one-way check with adjustable setting and integrated shut-off
 Material: corrosion-resistant valve body suitable for closed water and heating systems
 Operation: manual adjustment of opening pressure; manual flow shut-off
 Flow direction: straight inline to minimize pressure drop
 Typical installation positions: inline horizontal or vertical as specified by manufacturer guidance
How to use
Install the valve in the intended flow direction using appropriate fittings and pipe sealing methods for a 1/2" connection. Set the adjustable setting to the desired cracking pressure by turning the adjustment mechanism until the required one-way flow behavior is achieved. Use the integrated shut-off to isolate the downstream section for maintenance or balancing tasks. Verify there are no leaks after installation and adjust as necessary during system commissioning.
Usage recommendations
Inspect the valve periodically for proper operation and signs of wear. During initial commissioning, adjust the setting gradually while monitoring system flow to avoid unintended pressure changes. If used in heating systems, follow standard flushing and filtration practices to prevent debris from affecting the check mechanism.
