Safety Relief Devices
Sampling Cylinder Valves and Accessories
Saf-tee™ relief devices can be used with HOKE sampling cylinders as an inexpensive safety device or as a pipe size adapter for connecting valves in the make-up of cylinder assemblies.
Two basic models are available to satisfy most pressure ranges. Spring relief models are recommended for applications where re-closure is required.
Rupture Disc models are supplied with a pre-bulged rupture disc which provides excellent resistance to a broad range of hold-down plug and rupture disc to prevent damage due to torque transmission during assembly. A safety screen minimizes fragment release through the plug vents. The maximum operating system pressure should be limited to 80% of the nominal rating of the rupture disc for static operating pressure and ambient temperature. It should be limited to 70% if pressure pulsations occur or used at elevated temperature. The burst tolerance is within the ASME code guidelines.
