Lesker Edwards Needle Gas Valve

The Kurt J. Lesker Edwards LV10K manual fine control needle valve provides close control of a gas bleed or gas injection into a vacuum chamber. It can be mounted in a pipe-run or on a panel. A knob controls needle movement and, therefore, the gas leak rate through the valve. Resetting flow rates is aided by a pointer moving over a 100 division scale . (The scale can be rotated relative to the valve body as needed.)

The stainless steel needle is spring-seated in a replaceable brass valve seat. The constant spring pressure reduces the risk of needle damage. A fluoroelastomer 'O' ring provides the seal between the needle and the valve-body. Each valve port is fitted with sintered bronze filter to prevents particulate matter entering the valve and damaging the needle or seat.
