Key Benefits and Advantages
-
Sanitary Design Standards: The SR8 is built to meet the rigorous requirements of the life sciences and food industries. It features a nonporous, polished stainless steel body and internal components that prevent bacterial growth and product entrapment.
-
Clean-in-Place (CIP) and Steam-in-Place (SIP): To minimize downtime and ensure sterility, the SR8 is fully compatible with CIP and SIP protocols. Its robust construction can withstand the high temperatures and chemicals used in standard cleaning cycles.
-
Self-Draining Construction: The internal geometry of the valve is specifically engineered to be self-draining when installed in the correct orientation. This eliminates the risk of “puddling” or fluid retention, which is essential for maintaining a sterile environment.
-
Superior Flow Performance and Accuracy: Despite its compact size, the SR8 offers high flow coefficients (Cv) and precise pressure sensing. This allows for stable backpressure control even during significant fluctuations in process flow.
-
Tight Shutoff: The regulator is designed to provide excellent shutoff capabilities, preventing leaks and ensuring that the upstream pressure is maintained exactly at the desired setpoint.
-
Nonporous Polished Internals: All wetted parts are polished to a high degree of smoothness (typically 20 micro-inches Ra or better) to ensure that process fluids do not adhere to the surfaces and to facilitate easier cleaning.
-
Remote Setpoint Capability: For automated or distant control, the SR8 can be configured for remote setpoint adjustment, allowing operators to change pressure settings through a pneumatic loading signal.
-
Optional T-Handle: For manual adjustment in the field, an optional T-handle is available, providing an ergonomic and precise way to set the desired backpressure.
