VFX - MANUAL VALVE ACCESSORIES Venturi FX (VFX) can function with a variety of different products to control air temperature, decrease noise and improve ease of installation. Valve Accessories and Optional Products provided by Antec Controls include: CAUTION Hot Water Coils (VVHWC)
Page 11 Installation STEP 1 Hot Water Coils are only available in supply orientation and should always be located down stream of the supply Venturi FX. STEP 2 For single VVHWCs, position the bead connection so that it faces the airflow. For multibody VVHWCs, position the slip connection so that it faces the airflow.
Page 12: Electric Coils (Vvec)
VFX - MANUAL Electric Coils (VVEC) Electric Coils (VVEC) are devices installed with Venturi FX that control room environment by heating the air moving through the valve. The VVEC operates using standard building electrical power and is designed to optimize heat transfer.
Page 13 Mechanical Installation STEP 1 Electric coils are only available in supply orientation and should always be located down stream of the supply Venturi FX (VFX). STEP 2 Use the support method prescribed for the duct work in the job specifications.
Page 14: Silencer (Vvsil)
VFX - MANUAL Silencer (VVSIL) The Silencer (VVSIL) is a highly engineered 14-inch silencer specifically designed for the full spectrum attenuation of sounds produced by Venturi FXs (VFX). The packless design provides minimal disturbance in the airflow resulting in low pressure drops across the silencer.
Page 15: Valve Companion Connections (Vct)
Drawband clamps allow for quick installation or removal of the Venturi FX while minimizing damage from metal screws. Companion flanges are available for single body valves. Companion flanges are to be slid onto duct with a 1.5-inch overlap and mechanically fastened to the valve flange.
Page 16 VFX - MANUAL Slip-Connection Venturi FX (VFX) with Drawband Clamps Installation STEP 1 Slide drawband clamps completely onto the inlet and discharge ductwork. STEP 2 Mount the VFX by slipping both the inlet and the discharge one inch (1”) into the appropriately sized ductwork.

Page 19: Valve Actuator
Valve actuators are wired into the valve controller and are attached to the linkage bars of the valve. The actuator controls the position of the blade damper inside of the Venturi FX which controls the amount of air that flows through the valve. Valve actuators come in two main options: Standard Speed and High Speed.
