Document Outline
- A. General information
- B. Installation
- 1. Prior to installation, verify that the operating characteristics of the valve as described below are appropriate for the system in which it will be installed.
- 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. 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 has 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 fingertight).
- 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 actuator connection. The connection may be a 1/8 NPT female thread, 10-32 female thread, or an M5 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).
- 1. Prior to installation, verify that the operating characteristics of the valve as described below are appropriate for the system in which it will be installed.
- C. Operation
