Thermoplastic relief valves have small footprint
Three-port inline relief valve is ideal for systems requiring minimal footprint or where the use of a piping tee is not practical.
Pressure regulators provide protection for valuable downstream instruments and filtration systems by converting fluctuating or excessive inlet pressure to a preset maximum downstream pressure.
The PRA will routinely handle inlet pressure up to 10.3 bar and accurately maintain a downstream pressure from 0.3 to 8.6 bari.
The design of the PRA features two opposing, large area, frictionless rolling diaphragms.
Process pressure is applied to one of the diaphragms; air pressure is applied to the other.
Because the air pressure can be maintained with more accuracy than the force provided by a spring, the PRA offers greater sensitivity and less variance from set pressure than any thermoplastic pressure regulator previously available.
PRA is available in a number of rugged thermoplastics, including Grade 1 Type 1 PVC, Natural Polypropylene, and Kynar PVDF.
Elastomers are FKM or EPDM.
