The Belimo ZONE215N-10 is a 1/2 in. NPT female, 2-way on/off zone valve body: forged brass with a stainless steel stem and EPDM seat, Cv 1, 75 psi close-off, 300 psi body pressure rating and ANSI Class III 0.1% leakage, for chilled or hot water up to 50% glycol. It mounts a Belimo ZONE spring return actuator, sold separately.
Typically used on fan coil units, baseboards or other hydronic applications where fail-safe operation on 2-wire control is required, in hydronic systems with variable or constant flow. Designed to fit in compact areas where on/off control is required using 24 VAC or 120 VAC.
