Gas Pressure Regulator - an essential tool for gas handling system - is a device to control ‘downstream pressure’ from ‘upstream source’ in line with required working pressure that allows optimum gas to flow into the system. To use in Specialty Gases, the regulator must be made with stainless steel or chrome-plated brass depending on the purity level and corrosiveness of the pure gas or gas mixture. For Specialty gas Application Pressure Regulator are fitted with stainless steel diaphragm and mechanically linked to the poppet assembly to provide sealing integrity. Apart from being a high sensitive control device proper sealing diaphragm also prevents the diffusion of atmospheric oxygen into the carrier gases. For Pressure control either stainless steel Diaphragm (for low and medium pressure at downstream) or stainless steel Piston (for high downstream pressure) being used. Reduction of pressure in the regulator can be done either in single stage (one step Reduction) or in Double stage (Reduction in two steps). Inlet Pressure gauge indicates cylinder pressure or the source pressure. Outlet Pressure gauge indicates the pressure at which it is being delivered in the system.
How do you order for a Pressure Regulator? – There are two ways
We are given below a chart as a guide for selection of regulators. In case all parameters are not known to the user, at least working pressure, gas service and mounting can be intimated to us so that we can decide on the model and supply suitable regulator.
