Emerson Climate Technologies 1311-103 HVAC control

SKU CH-V18Q-XS51C

Two-way motorized zone valve with stainless-steel body, 37 Cv flow and 15 psi close-off pressure for 24 V AC systems

  • Stainless steel body resists corrosion for long service life
  • 24 V AC electric actuator provides reliable on/off control
  • 37 Cv rating delivers high flow capacity for efficient operation
  • 50 psi maximum allowable pressure suits demanding hydronic systems
  • 15 psi close-off pressure ensures tight shut-off performance

Emerson 1311-103 Motorized Zone Valve

This two-way motorized zone valve regulates fluid flow in hydronic heating and cooling systems. It features a stainless steel body with a 37 Cv flow coefficient and a 15 psi close-off pressure rating. The electric actuator operates on 24V AC power with an on/off control signal. It is designed for general-purpose HVAC applications.

Installers needing 24V on/off zone control

This valve suits professionals installing or servicing hydronic zoning systems that require a two-way stainless steel body rated for 50 psi maximum allowable pressure. It is not for systems needing modulating or proportional actuator control signals. Buyers requiring a three-way body pattern or a different voltage actuator should look at alternative models.

SPST contact simplifies wiring

The integrated SPST contact provides a straightforward electrical interface for end-switch wiring to the system controller. No separate transformer or complex relay logic is bundled with the actuator. The stainless steel construction eliminates the need for additional corrosion-resistant coatings in standard water-based loops.

Questions about this item

Do I need a 24 V AC transformer and a two-wire thermostat to drive the actuator?

Yes — the electric actuator requires a 24 V AC supply and an on/off control signal, so a compatible transformer and SPST thermostat or controller are required.

Will the 15 psi close-off pressure hold against my existing 50 psi system pressure?

The valve is rated for 50 psi maximum allowable pressure but only 15 psi close-off, so it can stay in the line at 50 psi but may not seal tightly against that full pressure when closed.

How can I confirm the valve is opening and closing correctly after wiring?

Apply the 24 V AC signal and watch the actuator shaft; the valve should move from fully closed to fully open, and removing the signal should return it to the closed position.
