Document Outline
- A. General Information
- B. System Design/Product Selection
- 1. When selecting the valve model and configuration, verify the following information.
- a. Verify the materials of construction are compatible with the intended process gas.
- b. Verify the pressure and temperature ratings are acceptable for the intended application.
- c. Verify the actuation pressure supply is appropriate.
- d. Verify that the flow capacity (Cv) of the valve is appropriate for the application.
- 2. Valves can be used under a large variety of operation conditions. The system designers shall decide product selection based upon their own analysis and testing to verify acceptable operation with specific equipment.
- 1. When selecting the valve model and configuration, verify the following information.
- C. Installation
- 1. Verify the pressure rating is acceptable.
- 2. Inspect the valve to determine the flow path through the valve and how the valve will be installed in the system.
- a. An inlet (upstream) port is defined as a port connected to the region below the valve seat and may be labeled with an “IN” marked into the body near the port.
- b. An outlet (downstream) port is defined as a port connected to the region above the seat and below the diaphragm. The outlet port is usually not labeled, but may be marked “OUT”.
- c. The traditional flow direction is inlet to outlet, but AP Tech valves may be employed in either traditional flow direction or the reverse.
- d. On Series DV Monoblock valves the port that is common with the block valves is marked with a “C”. No other marking is shown. Refer to Technical Bulletin 205 for schematics of the monoblock configurations and more detailed information.
- 3. Install the valve using the appropriate method described below.
- a. For tube stub connections, weld connectors or other components to the tube stubs per standard industry practice (reference SEMI standard F78).
- b. For metal face seal connectors, assemble connections per standard practice described by fitting supplier (typically 1/8 turn past finger-tight).
- c. For compression-type connectors, insert the tube into the fitting until it stops. Tighten the fitting by applying 1-1/4 turns of nut rotation.
- d. Most valves can be attached to panels or mounting plates using the 10-32 or M5 female thread mounting holes located in the bottom of the body (valves with M5 mounting holes will be marked with a “5” on the bottom of the body). Special configuration...
- 4. Connect a nitrogen or clean dry air actuation pressure supply to the valve actuation port connection. The connection may be a 1/8 NPT female thread, 10-32 female thread, or M5x0.8 female thread depending on the valve model.
- 5. After installation, perform a leak test of all connections and welds per standard industry practice (reference SEMI standard F1).
- D. Indicating Switch Option Installation
- 1. IS option for AK/AP/AZ3000, AP3113, AP3130, or AK/AP/AZ3200:
- a. Review the following specifications to verify the switch is appropriate for the installation.
- b. Connect blue lead to common output.
- c. Connect brown lead to normally closed input (the circuit will be closed when valve is closed).
- d. Connect black lead to normally open input (the circuit will be closed when valve is open).
- 2. ISO and ISC option for AK/AP/AZ3550, AK/AP/AZ4550, or AP3700:
- a. Review the following specifications to verify the switch is appropriate for the installation.
- b. Connect common input to one lug terminal (solder wire or use .110 quick disconnect receptacle).
- c. Connect signal input to other lug terminal (solder wire or use .110 quick disconnect receptacle). For ISO option, the circuit will be closed when the valve is open. For ISC, the circuit will be closed when the valve is closed.
- 1. IS option for AK/AP/AZ3000, AP3113, AP3130, or AK/AP/AZ3200:
- E. Operation
- 1. Perform the following to close the valve.
- 2. Perform the following to open the valve.
- a. Apply actuation pressure to the valve. For the AK/AP/AZ3571 and AK/AP/AZ4571, actuation pressure on port “2” or on both ports “1” and “2” will fully open the valve and actuation pressure only on port “1” will partially open the valve to a metered f...
- b. If an indicating switch option was installed, verify that the output signal changed states.
- 3. When a valve is in the closed position, the inlet ports are isolated from the outlet ports. When a valve is in the open position, all ports are common.
