Features and Benefits Direct reaction design, high accuracy of pressure adjustment. Diaphragm type, quick response against pressure change. Big inner chamber, avoid noise. Inlet pressure balancing function, fluctuating inlet pressure doesnot influence outlet pressure. Stainless steel and bronze parts, corrosion resistant. If required, pressure gauge can be installed.
