[. . . ] Low- and Mid-Flow Metering Valve Kits for molstic-STM P/Ns 401885 and 401666 Instruction Sheet The 1/4 in. These valves provide a measure of flow control for use when calibrating devices that do not have their own flow control means. [. . . ] METERING VALVE ONTO MOLSTIC-S PLATFORMS WITHOUT REGULATORS Use the following procedure to install the metering valve kit onto the molstic-S platform that does not have the integrated regulator: Attach the valve bracket to the base of the valve using the two included #10-32 socket head cap screws, the two #10 flat washers and the two #10 lock washers. 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). 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). 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. [. . . ] In order to make extremely fine flow rate adjustments the metering valve can be used in combination with small adjustments in the supply pressure.
