PR-59
Designed for low and high pressures up to 4000 psig inlet, the PR-59 Series pressure reducing regulator controls high flow with its Cv flow coefficient of 1.2. Though normally supplied without self-relieving capability, this feature can be added as an option.
While primarily designed for use with gas streams, the PR-59 can be used with virtually any liquid systems that are compatible with the seals.
A large size piston sensor gives good sensitivity of control even at low outlet pressures and the Kel-F® valve seat assembly gives normal bubbletight shutoff.
- 316L stainless steel, Brass and MONEL® body construction
- Optional self-relieving feature
- Balanced poppet valve design for constant pressure control
- Viton® seals (other elastomers optional)
- PCTFE seat
