Angle & Inline Valves
General Guidelines


Installation and Orientation

Angle and inline valves can be installed using one of five industry standard port connections. Custom configurations are also available upon request. Valves up to and including 4-inch ports can be installed in either a vertical or horizontal orientation. Valves with 6-inch and larger ports must be installed in a vertical orientation, as shown in the figure below. The bottom port is usually oriented towards the vacuum environment. Mounting in this fashion minimizes the in-vacuum volume and also aids poppet sealing when the side port is vented to air.

Sealing
Angle and inline valves can be sealed via manual or electropneumatic actuation. All valves up to 3-inch ports will seal against 15 psi differential atmospheric pressure in either a bottom or side port direction. Those with 4-inch and larger ports should be installed with vacuum at the valve seat port only, shown as bottom port. Electropneumatic angle and inline valves with ¼-inch to 1½-inch diameter ports are fitted with air-open / spring-close actuators. Valves with 2-inch or larger diameter ports employ air-open / air-close pneumatic actuators. Custom actuator designs are available on request.

Bakeout- Air control solenoid valves must be removed or remotely mounted for valve maximum bakeout conditions. The solenoid valve temperature should not exceed 50°C. Pneumatically actuated air cylinder seals are Viton® elastomer O-rings and therefore have a temperature limit of 150°C.

Maintenance- Actuator and poppet mechanism may be removed through the bonnet flange for seal replacement, cleaning or retrofitting without removing the valve body from the system. Refer to instruction manual for details.

Leak Testing- Each valve is tested using a helium mass spectrometer leak detector calibrated for a minimum sensitivity of 2x10-10 std. cc/sec of Helium. Internal welds are inspected for pits, cracks, and other irregularities which may cause virtual leaks.
