BUTTERFLY HVAC VALVE 4" EPDM SEAT 8 LUG CAST IRON 24vac actuator 175psi F.O.B.: Chandler, AZ 85246, Valves are new. Questions: contact Dick (602) 369-5522 VF Series Standard-Pressure, Standard-Temperature Butterfly Valves are specifically designed for a wide range of Heating, Ventilating, and Air Conditioning (HVAC) applications, including two-position control of hot, chilled, or condenser water, and 50/50 glycol solutions. All valves are factory tested for bubble-tight shutoff at 100% of the fully-rated pressure. These valves are also bidirectional, allowing positive shutoff with the flow in either direction. Two-way configuration.

The Series 70 features on-off or modulating control. Bray’s Series 70 electric actuator has many advantages over other actuators including: UL,CSA and CE certification of most units Wiring directly to the terminal strip without interference from other components Simple and unique manual override handwheel system Lowest profile and lightest weight actuator on the market Simple finger or screwdriver adjustment of travel limit cams without interference from other components Highly visible valve status display on most units Designed like a junction box, the Series 70 offers by far the easiest access to terminal block wiring, cam adjustments and switch installation. Therefore, the time required for field start-up and adjustment is greatly reduced, and maintenance can be performed with assured ease and safety. Features Travel Limit SPDT Switches. Travel Limit SPTD Switches Bray has provided two SPDT mechanical switches as standard. These durable, high quality switches are mechanically isolated and electrically independent. The dedicated circuits eliminate any voltage crossover between the switches. This switch combination is used for both open and closed positions of the valve and requires only one cam for each direction of valve travel. Bray’s design provides synchronicity between motor control and position display. Switches are easily accessible without interference from other components. Each switch is marked with open or close labels and the cams are color coded, green for open and red for close, eliminating the possibility of incorrect wiring. Cam Adjustment Conduit Entries Bray’s patented cam design is an outstanding feature of the Series 70. Cams for each switch are infinitely adjustable by finger touch or screwdriver with no special tools needed. The adjustment knobs rotate the specially formed cams. Each cam is color coded – the red adjustment knob controls the red cam (close position), and the green knob controls the green cam (open position). Standard factory setting allows 90° travel between open and closed positions. Conduit Entries; Two connections in either NPT or metric threads. One entry is for power, the other for control wiring. Explosion Proof Enclosure Series 70 Electric Actuator; The Series 70 optional waterproof/ explosion proof unit is UL NEMA 4,4x listed and certified to specifications for USA & Canadian hazardous locations Class-I C&D Div 1&2; Class-II GRPS EF&G Div 1&2. The rugged, heavy duty housing contains precision machined bores and flanges to meet flame path requirements. Waterproof/Explosion proof models are currently available with 800 to 2,000 lb.-in. output torque, continuous or intermittent duty. [A] TERMINAL BLOCK: The actuator switches are pre-wired to an easily accessible terminal block. Terminals are clearly identified for customer wiring. The block has been placed near the two conduit entries with ample room for running wire leads. A wir- ing diagram is included inside the cover for easy reference. The ground wire screw is plated green and positioned for easy access. [B] VALVE STATUS DISPLAY: Prominently labeled and color coded – yellow for open, red for closed – the display indicates valve position through the full range of travel. The display can be seen from almost any angle. Made of high impact, heat and chemical resistant clear polycarbonate, this display withstands caustic wash down and offers excellent corrosion protection. Potential leak paths are eliminated since the indicator cover utilizes a static seal, not a dynamic seal. [C] INTERPOSING RELAY: The time delay provided by the Interposing Relay will protect the switches and gears from the controller’s instantaneous command signal reversal. This feature also allows for parallel wiring of multiple actuators. [D] MANUAL OVERRIDE: A manual override handwheel is standard on all models to rotate the valve without electrical power. A yellow caution stripe around the handwheel hub becomes visible when the handwheel is engaged for manual operation. {E] AUTOMATIC POWER CUTOUT SWITCH: The Series 70 is supplied with a SPDT mechanical switch which cuts power to the motor when the handwheel is engaged for manual operation. [F] O-RING SEAL FOR WATERTIGHT ENCLOSURE: The large seal between the cover and base provides a waterproof seal and prevents internal corrosion. The Bray Series 70 O-ring seal is a far superior design to commonly used gaskets. [G] ENCLOSURE: The Series 70 waterproof unit is UL NEMA 4, 4x listed. Die-cast aluminum cover and base are high-quality polyester powder coated for exceptional corrosion, wear, impact and ultra-violet resistance [H] CAPTIVE COVER BOLTS: The cover is attached to the base by stainless steel bolts. When the cover is removed the bolts are held captive in the cover. This prevents time consuming problems caused from lost or misplaced bolts. -------------------- Buyer gets ONE (1) New Johnson 4" Valve Model # VFC-040HB-722D4 with One (1) New Bray 24vac Actuator VA-9072-12, assembled, with factory wiring diagram, FOB Chandler, AZ. 85246 USA.
