Description
The S9 regulator is a direct acting, dual-stage pressure regulator with an integral slam-shut valve (SSV) and an optional token Internal Relief Valve (IRV).
The S9 features a variety of body configurations, end connections, and integral overpressure protection options.
The dual stage design provides improved accuracy and minimizes delivery pressure fluctuations as inlet pressures vary.
The available over pressure protection options include a token IRV, Limited IRV, over pressure shut off (OPSO) device, under pressure shut off (UPSO) device and excess-flow shut off (EFV).
Built on decades of experience and refined for North America, the S9 provides a level of safety and reliability for commercial applications that cannot be achieved with traditional lever-style regulators.
