Product Bulletin Issue Date July 2018 © 2018 Johnson Controls, Inc. 1 Code No. LIT-977175 www.johnsoncontrols.com Flare Valves 1/2-Inch 2-Way and 3-Way The 1/2-inch flared valve line accurately regulates the flow of hot or cold water in small Heating, Ventilating, and Air Conditioning (HVAC) terminal units. These 1/2-inch valves are available with a factory-installed V-3000-1 exposed type pneumatic actuator; enclosed actuators (V-3000-2) are also available (order separately). This valve style is available for field mounting the VA-805x Series electric actuators. Figure 1: 1/2-Inch Flare Valves Features and Benefits 1/2 in.

The V-3766, V-3966, and V-4332 1/2-inch valves are available with a factory-installed V-3000-1 exposed type pneumatic actuator. V-3000-2 enclosed actuators are also available (order separately). The VB-3766, VB-3966, and VB-4322 1/2-inch valve bodies are available with or without a factory-coupled VA-805x electric actuator. IMPORTANT: When using an electric actuator with these 1/2-inch flare valves, only use VA-805x Series electric actuators. Use of other actuators may cause malfunction of the valve or damage to the valve. The valve and actuator provide a Push-Down-To-Close (PDTC) combination for Normally Open (N.O.) applications and a Push-Down-To-Open (PDTO) combination for Normally Closed (N.C.) applications. All valves contain a modulating plug, which provides an equal percentage relationship between valve travel and flow at a constant pressure drop. A molded composition disc that ensures tight shutoff is bonded to the valve plug assembly and can be removed for servicing. Operation V-3000-1 and V-3000–2 Actuated Valves Air pressure from a pneumatic controller moves the diaphragm of the actuator, which moves the piston against the forces of the internal spring and the fluids. The piston moves the valve plugs to a position where the diaphragm pressure and the spring force balance against the fluid forces. These fluid forces cause the operating range to shift from the nominal spring range. Reducing the air pressure to the diaphragm of the actuator allows the spring to return the valve plug to its normal position. VA-8050-1 and VA-8051-1 Actuated Valves The controller sends a 24 VAC signal to the up or down terminal on the circuit board depending on the desired movement of the valve. This signal causes the motor to rotate in the proper direction and, through the lead screw and lever, move the valve stem and plug assembly up or down. When the controller stops sending a signal, the valve stem and plug assembly remains in place. When the controller closes the valve, a shutoff force builds up. When this force reaches 50 pounds, the lever activates a force sensor that stops the motor. Field calibration of the force sensor is not required. The actuator maintains the shutoff force even if power to the controller is lost. When the controller signals the valve to move in the opposite direction, the shutoff force is reduced and the valve modulates. On VA-8051-1 actuated valves, an internal position feedback potentiometer is connected to the R, W, and S terminals. Specifically the wiper is connected to W. The wiper is at the R end when the actuator is retracted and at the S end when the actuator is fully stroked.

The exposed model (V-3000-1) is designed for installation in a protected location. The enclosed model (V-3000-2), available separately, is designed for installation in a location where the actuator might be subjected to tampering. See Table 1 for actuator sizing selection. Both models of the V-3000 actuator have a molded synthetic elastomer diaphragm design. This molded diaphragm provides a constant effective area throughout the valve stem stroke. All parts are protected by a sturdy, die-cast aluminum housing. Loosening the single set screw allows removal or repositioning of the actuator housing without disturbing the rest of the valve assembly. A V-9502 Series Valve Positioner is available separately for use on the exposed model in applications where sequential operation is desired or additional positioning power is necessary. The V-9502 Pneumatic Valve Actuator Positioner is a precision relay device designed to operate a valve actuator in applications requiring stable, accurate control. The positioner provides maximum positioning power to resist external forces, which might otherwise overcome the actuator. See Table 2 and Table 3 for ordering information. VA-8050 and VA-8051 Series Electric Actuators The VA-8050-1 and VA-8051-1 Series Electric Actuators are synchronous motor-driven, non-spring return actuators that feature a force-sensing mechanism that ensures a constant 50 pound seating force.

Includes a 3,400-ohm position feedback potentiometer for remote position indication to meters. Valve Body Types for Electric Actuators For floating/incremental signal non-spring return actuators (VA-8050 and VA-8051), the PDTC (VB-3766-1) body type meets the needs of any HVAC application. The PDTO (V-3966-1) type is not available with these actuators. 6 Flare Valves 1/2-Inch 2-Way and 3-Way Product Bulletin Table 2: Ordering Data for Pneumatically Actuated 1/2 in.
