User manual FLUKE MID-FLOW METERING VALVE KITS FOR MOLSTIC-S

[. . . ] Low- and Mid-Flow Metering Valve Kits for molstic-STM P/Ns 401885 and 401666 Instruction Sheet The 1/4 in. molstic-STM is delivered with integrated shut-off/metering valves. These valves provide a measure of flow control for use when calibrating devices that do not have their own flow control means. [. . . ] The long side of the bracket should be perpendicular to the direction of flow through the valve. Using a pair of properly sized wrenches, break the connection between the downstream end of the ® filter element (1) and the female VCR swivel nut (2) on the inlet of the molstic-S. Do not disassemble the parts on the inlet side of the filter element (1). Discard the VCR gasket, which is for one-time use. Thread the included double female VCR union (non-swivel type), (3), onto the inlet fitting of the metering valve. Leave it approximately one full revolution from the fully stopped position. VCR gasket (P/N 102183) securely against the sealing surface inside the double female VCR union (non-swivel type) (3). Install the filter (1) and upstream plumbing into the female VCR union (3). Hold male body stationary with a backup wrench. Tighten the female nut 1/8 turn past finger-tight. Place the flat side of the 60 mm nut plate under the molstic-S platform (see figure below). Align it with the holes in the platform and the valve bracket. Thread the socket head cap screws through the valve bracket and tighten securely into the nut plate. Do not adjust the supply pressure to the 1/4 in. metering valve in excess of the maximum operating pressure of the molbox: 600 kPaa (87 psia) for molbox1-A700K; 250 kPaa (36 psia) for molbox1A350K. INSTALLATION OF 1/4 IN. METERING VALVE ONTO MOLSTIC-S PLATFORMS WITH REGULATORS Do not attempt to completely close off flow using the 1/4 in. They are not designed to be used as shut off valves. Damage to the valve seat can occur. PARTS INCLUDED WITH 1/4 IN.
