THE NEW SERIES ZV2 AND 3ZV2 ZONE VALVES are perfect for use with temperature controllers and thermostats to control temperature in HVAC systems. The valves control the flow of hot and cold water in the HVAC system thereby controlling temperature. Units come in two-way and three-way construction and incorporate a bidirectional motor. They feature an easy turnkey removable actuator design for ease of installation and are available in 1/2?, 3/4?, 1? and 1-1/4? sizes. Zone valves incorporate manual overrides, and are for use with supply voltages of 120 VAC, 24 VAC, or 220 VAC. Inputs available are floating or modulating with 4 to 20 mA or 0 to 10 VDC. Modulating valves feature a motor timer that automatically turns off the motor after the full stroke to extend motor life.• Service: Compatible fluids. • Body: 3-way. • Line Size: 1/2" to 1-1/4". • End Connections: Female NPT (optional BSP, sweat connections). • Pressure Limits: Maximum: 300 psi (20.7 bar); Close-off: 43 psi (2.96 bar). • Temperature Limits: Ambient: 32 to 104°F (0 to 40°C); Process: 37 to 201°F (3 to 94°C). • Wetted Materials: Brass, stainless steel, NBR. • Flow Characteristic: Quick opening. • Input: Floating: 3-wire; Modulating: 0 to 10 VDC or 4 to 20 mA (24 VAC power only). • Power Requirements: 120 VAC or 24 VAC, ±10%, 50/60 Hz.
