Product information

Description

The Anti-freeze valve Samee NQSD32 for monoblock heat pumps, 1 1/4" (DN 32) is a safety device developed to protect hydraulic circuits from freezing during low ambient temperatures. Designed for direct integration into the piping of monoblock heat pump systems, the valve opens to allow flow or bypass when temperatures approach freezing, preventing solidification of refrigerant or heat-transfer fluid and ensuring continuous, safe operation of residential and light-commercial heating and cooling loops.

Advantages

The Samee NQSD32 valve provides passive, automatic protection without the need for additional electrical components or control logic. Its compact DN 32 connection and standard 1 1/4" sizing permit straightforward installation in existing piping runs used by monoblock heat pumps. Constructed to operate reliably in low-temperature environments, the valve reduces the risk of costly freeze damage and downtime while maintaining hydraulic circuit integrity.

Suitable for

  • Residential monoblock heat pump heating circuits
  • Light-commercial heat pump installations and small server rooms
  • Hydronic loops exposed to sub-zero ambient temperatures
  • Retrofit or new installations requiring freeze protection

Key specifications

  • Connection size: 1 1/4" (DN 32)
  • Function: automatic anti-freeze / flow protection for hydraulic circuits
  • Installation type: inline, fitted into supply or return pipework
  • Suitable media: refrigerant circuits or water/glycol heat-transfer fluids compatible with heat pump systems
  • Operating environment: low-temperature conditions typical for heating/cooling installations

How to use

Install the anti-freeze valve inline in the supply or return piping of the monoblock heat pump circuit with the correct flow direction. Ensure connections are tightened to manufacturer-recommended torque and that pipework is supported to avoid strain on the valve body. Verify compatibility of the heat-transfer fluid and pressure ratings before commissioning. After installation, perform a pressure test and a functional check at low ambient or simulated low temperature to confirm the valve operates as intended.

Usage recommendations

Position the valve where it is accessible for inspection and maintenance and avoid locations subject to mechanical damage. Use with compatible water/glycol mixtures if the system demands antifreeze additives. Periodically inspect for leaks and verify operation after seasonal shutdowns or prolonged idle periods to ensure continued freeze protection.
