This 35mm Compression Pump Valve connects directly to large domestic and commercial central heating circulating pumps. Specifically, it provides a durable, secure, and highly reliable method of isolating the water flow to and from your heating pump during maintenance or replacement. Furthermore, thanks to the easy-to-operate quarter-turn lever handle, you significantly speed up servicing by eliminating the need to drain down the entire heating network.
Therefore, this 35mm compression lever pump valve works perfectly for high-capacity domestic heating networks, commercial plant rooms, and district heating systems. Additionally, it easily handles demanding applications, such as the safe, unrestricted fluid isolation in high-volume commercial circulating loops.
The valve features a robust construction with a high-quality plated brass body and a heavy-duty captive flange nut for a secure, flush seal against the pump housing. Moreover, the material is completely corrosion-resistant, built to withstand continuous thermal cycling, and rated for PN16 pressure networks to ensure long-term, leak-free operation. As a result, this solid build makes it fully reliable for high-demand residential, commercial, and industrial heating installations.
Key Features & Benefits:
Full Flow Design: The valve’s internal ball design allows for completely unrestricted water flow into the pump. Consequently, you achieve maximum system efficiency and maintain optimal pressure without the restrictive pressure drops or friction losses associated with smaller standard valves.
Direct Pump Integration: The design includes a heavy-duty swivel female running nut. For example, if you are connecting this directly to a high-capacity commercial circulating pump, this integrated nut guarantees a perfectly flush, leak-free seal without needing extra fittings. Ultimately, this allows you to create fully streamlined and secure plant room pipework.
Quick Quarter-Turn Operation: The ergonomic red lever handle acts as a highly efficient control mechanism. Importantly, it completely opens or closes the water supply with a simple 90-degree turn. Therefore, it guarantees fast and immediate isolation during emergencies or routine pump maintenance.
Durable Plated Construction: The high-quality brass body with a clean silver finish prevents structural degradation over time. In particular, this solid material also provides excellent temperature and pressure resistance, effectively handling both heavy-duty heating loops and commercial hot water applications with total reliability.
