Description Specifications Literature Description The PR-50 Series pressure regulator is designed to meet the demands for outlet pressures up to 2000 PSIG while maintaining superior corrosion protection.For reliability in operation, this precision regulator features a stainless steel body (optional brass) which provides maximum corrosion resistance and safety. The optional self-relieving feature provides an additional level in operational ease, as it allows for trapped downstream pressure to be safely vented to atmosphere through the bonnet.To prolong regulator life, this unit is supplied with an integral inlet filter which protects the seat against any foreign contamination introduced by the upstream supply.
