PA1/PL1 Bio-Sanitary Pressure Reducing Regulators

The Models PA1 and PL1 are stainless steel pressure reducing regulators designed to handle small to mid-capacity flow rates in sanitary biotechnical process piping systems.

These units are capable of control ling outlet pressure to a level between 2 and 140 psig (.13 and 9.6 Barg).

Angle style body with bottom inlet and side outlet.

Unit is cleaned to Cashco Spec. #S-1576. Interior of body polished per ASME BPE 1997 (SFV-4 10 micro-inch Ra finish).

Interior and exterior surfaces are electro-polished. A “non-wetted” guide in the topworks above the diaphragm provides stability at all set points.

Widely applied for processed food production — confectionery, beverages, nutritional supplements and artificial sweeteners.

May also be used in cosmetics production and specialty chemicals.

Would be found supporting fermenters, batching tanks, cookers, autoclaves, dryers and other similar equipment.
