Resideo PCV125 Check Valve
The Resideo PCV125 is a professional-grade 1-1/4" hydronic check valve engineered to eliminate ghost flows and reverse circulation in high-demand residential and light commercial systems. Specifically optimized for AquaPUMP PC3F2699IUF00 series circulators, this inline flow check ensures directional stability in closed-loop heating and chilled water applications. By maintaining a positive seal during pump cycling, it protects expensive boiler heat exchangers and prevents heat migration into zones where it isn't required.
Constructed for durability in professional HVACR environments, the PCV125 check valve manages a significant 62 GPM flow capacity while sustaining a maximum working pressure of 150 PSI. It is rated for fluid temperatures reaching 200°F, making it a reliable choice for primary-secondary piping and radiant manifold supply lines. The low-cracking pressure design minimizes head loss, ensuring that your hydronic pump protection strategies do not compromise overall system pump curves or electrical efficiency.
Key Benefits:- Specifically sized as a 1-1/4 inch circulating pump check valve for seamless integration with Resideo PC3F series wet rotor pumps.
- Features high-performance seals to prevent thermal siphoning and backflow in multi-zone hydronic loops.
- Robust performance ratings: Supports up to 62 GPM and 150 PSI maximum pressure.
- Wide temperature range up to 200°F, suitable for high-mass boiler systems and solar thermal applications.
- Reduces hydraulic noise and mechanical stress on the pump impeller by ensuring consistent directional flow.
Does this valve work with other pump brands?
While technically a 1-1/4" check valve, it is purpose-built as an internal component for Resideo AquaPUMP PC3F models to ensure exact tolerance and performance matching.
Will this prevent banging or water hammer in a zone?
Yes, by preventing the oscillation and reverse flow that often occurs when a zone valve closes or a high-head pump stops, the PCV125 significantly reduces system noise.
Can I install this on the suction side?
Standard practice for directional flow in heating usually places the check valve at the pump discharge to prevent back-pressure, though specific system designs vary.
