UHP VCR Tied Diaphragm Pressure Reducing Regulators

DRA 200 Series is the tied-diaphragm pressure reducing regulator designed to use at the special manufacturing line of ultra-high pure semi-conductors, bulk gas lines, valve manifold boxes and other laboratory. Tied-diaphragm type regulator connects the diaphragm and main valve together which prevents pressure loss and so maximizes safety of the regulator. Specially , this model is very useful to protect the diaphragm from toxic gas, ignition gas,high corrosive gases,etc and patent-applied locking plate system is adopted (patent no.10-0753280),too. As Max Inlet pressure upto 3500 psig(241 bar) and outlet working pressure upto Max 250 psig (17 bar), you can select each model based on outlet pressure range. You can select 2 ports,3 ports, 4 ports types as per each application. In order to prevent generation of impurities, it is cleaned DI water and the internal surface is treated to the grade of E.P 10 Ra and 5 Ra. All the process assembly, welding, testing and cleaning of this DRA 100 series is carried out and thoroughly managed in the 100-class and 10-class clean room. 

Drastar regulators are designed and manufactured for easier operation by equipping with the DRASTAR’s own developed “push and lock” type(patent number 1086199) handle that completely prevents the slight change of pre-set value that can be caused by the vibration from outside or minute vibration at the gas pipeline. you can prevent the slight-changing of pre-set value just by pushing the handle and reset the value freely by drawing the handle. This push and lock system has been created and applied patent for DRASTAR regulators.
