Problem Preventing Procedure SECTION I — INSTALLATION Operating medium from air loader or sensing element Fig. 1 — For controlled pressures above 25% of Inlet pressure (Compressible Fluid). 1. Provide space above, below and around the valve for removal of parts during maintenance. 2. Blow or flush out the pipe lines thoroughly before installing the valve. 3. Remove raised faces of iron or steel line flanges to which bronze valves are to be bolted.
Starting Up: SECTION II — OPERATION For installation, adjustment of loading device and operating details, consult the proper instructions pertaining to the particular type of loading, sensing or other operating device. 1. Open inlet stop valve. 2. Close outlet stop valve. Overall Valve Dimensions 3. Dispose of condensation, dirt, etc., by opening the strainer blow-off valve. For overall valve dimensions — face-to-face, height, etc., — consult the drawing which applies to the valve in use. 4.

SECTION III — MAINTENANCE Diaphragm Cover Leslie control valves may be dismantled without removal from pipeline when maintenance checks are desired. Diaphragm (2 leaves) Play Safe! Use Only Genuine Leslie Replacement Parts Diaphragm Disc All Leslie control valves are made of high quality materials, are time-tested and backed by more than a half century of knowhow. Machining is done by expert craftsmen and each valve is inspected and service-tested before shipment to you.
To Install Seat Ring 1. Carefully clean threads and joint contact surfaces on seat ring and in the valve body. 2. Make sure joint surfaces are undamaged. 3. Use a light coating of Never-Seez or similar lubricant on the first two threads only of seat ring. Screw seat ring into valve body threads and pull up tight with wrench. 4. Tap handle of socket wrench with hammer to lock seat ring in place. Hard Seats Only: 5. Lap in main valve and seat ring carefully. Use very fine lapping compound.
GPK-1T, GPK-2TC, GPK-2T AND GPK-4T PRESSURE REDUCING VALVES SIZES 1 ⁄2" THROUGH 4" For TROUBLE FREE OPERATION and TIGHT SHUT-OFF carefully follow the MAINTENANCE PROCEDURES outlined in this INSTRUCTION. Diaphragm Cover HOW TO IDENTIFY YOUR VALVE TYPE Crush Limit Ring Diaphragm(s) Bolt GPK-1 T— Fitted with three (3) stainless steel diaphragms. GPK-2T—This is a converted GPK-1T fitted with a SUPERFLEX diaphragm and a metal spacer ring to control diaphragm crush.
3. Install main valve, main valve spring, bottom cap with guide bushing and bottom cap gasket. Tighten bottom cap. 4. Place travel stop washer over upper end of main valve stem followed by diaphragm disc (GPK-2T and GPK2TC, sizes 1” through 2” do not have a travel stop). 5. Check height of disc. IMPORTANT: Height of diaphragm disc MUST be correct to obtain TIGHT SHUT-OFF of main valve. See Clearance Table and sketch for details.
