INSTALLATION

Inspection Inspect the package for damage. If damaged, notify the appropriate carrier immediately.

If undamaged, open the package and inspect the device for obvious damage. Return

damaged products.

Requirements • Tools (not provided): Pipe wrenches

• Training: Installer must be a qualified, experienced technician

• Appropriate accessories

Caution:

• Install the valve with the flow in the direction of the flow arrow (“A” port is the inlet and

“AB” port is the outlet).

• Do not exceed the ratings of the device.

• Avoid locations where excessive moisture, corrosive fumes, or vibration are present.

Mounting 1. The valve should be mounted in a weather protected area in a location that is within the

ambient limits of the actuator. When selecting a location, allow sufficient room for valve

linkage, actuator, and other accessories and for service of the product.

2. The preferred mounting position for the valve is with the valve stem vertical above the

valve body. Avoid mounting the valve so that the valve stem is below horizontal.

3. On steam applications where the ambient temperature approaches the limit of the

actuator, the valve stem should be mounted 45° from vertical.

4. The VB-7212-0-4 series of flared valve bodies conform to SAE 45°. The valves must be

piped with the “A” port as the inlet and the “AB” port as the outlet.

CHECKOUT

1. Make sure the valve stem operates smoothly before installing the valve linkage and the

actuator.

2. If the stem does not operate smoothly, it may indicate that the valve was twisted or

crushed during installation or that the stem was bent by rough handling. These

conditions may require that the valve be replaced.

3. After the piping is under pressure, check the valve body and the connections for leaks.

4. After the valve linkage and the actuator are installed, check their operation.

a. Power the actuator and run the valve to the stem down position. Make sure the

linkage and valve stem stroke fully. At the stem down position, the valve should shut

off tightly.

b. For spring return actuators, allow the actuator to spring return to the stem up

position. Again, the valve stem and linkage should operate smoothly. At the stem

up position, the valve should be in its full open position.
