Caleffi Z200537 Motorized Zone Valve

The Caleffi Z200537 Motorized Zone Valve is a 2-Way, 3/4 inch valve designed for precise HVAC zoning with electric spring-return actuation. The brass body, stainless steel stem, and EPDM rubber seal deliver durable performance for hot and chilled water in heating and air conditioning systems. This model features a normally open (NO) valve position and fast timing for responsive control.

Key specifications ensure reliable operation in demanding environments: a 24 V AC input, 60-second open and 6-second close timing, and a 7 CV flow capacity. With lead-free construction and compliance to UL (Canada and US), NSF/ANSI 372, and ICC-ES PMG standards, the Z200537 is built for code-compliant, long-lasting service. The push-button mounting simplifies installation and servicing in tight mechanical spaces.
