With the introduction of the new SLR-1 and SLR-2 self-loading regulator valves, this company now offers more choices for pressure regulation. The SLR-1 consists of a DA4 high-performance, pressure-loaded, flow-to-open, pressure-reducing regulator with either this company’s P1 or Fairchild Model 10 pressure-reducing regulator mounted onto it. The inlet of the main valve will divert into the P1/Fairchild, which in turn reduces the pressure to the level that is required inside the cover dome in order to maintain the setpoint of the main valve. Similar to the SLR-1, the SLR-2 employs a P1/Fairchild valve mounted onto a DA4 pressure-reducing regulator. However, unlike the SLR-1, the P1/Fairchild used on the SLR-2 is not self-relieving. Instead, the cover dome pressure will constantly bleed through a filter and check valve, and dump back into the outlet of the main valve. — Cashco, Inc., Ellsworth, Kan.
