Description
The RS series pressure-reducing regulators are suitable for most gases and liquids.
The RS series regulators feature various poppet designs, a choice of sensing types (diaphragm or piston), and seat and seal materials to accommodate a variety of pressure, temperature, and flow conditions.
The RSH series regulators are a high-pressure version of the RS series regulators, and the LRS and LPRS series are low pressure, high-accuracy versions of the RS series regulators.
Features- Diaphragm sensing
- Large diaphragm for higher accuracy
- Diaphragm materials: PTFE and 316L SS for most pressure control ranges
- Bottom mounting
- Low torque minimizes stem wear
- Nonventing
