Thermoplastic pressure regulators are introduced
The Series PRA (photo) is a pneumatically controlled pressure regulator, also called a pressure-reducing valve, that maintains a constant downstream pressure from 5 to 125 psi with high accuracy over varying flowrates. The new design uses compressed air and two rolling diaphragms to control liquid pressure with greater accuracy than spring-loaded regulators. Suitable for highly corrosive and ultra-pure chemicals, the PRA will routinely handle inlet pressures of up to 150 psi. The regulator’s design features two opposing large-area frictionless rolling diaphragms. Process pressure is applied to one of the diaphragms and 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 previously available thermoplastic regulators. — Plast-O-Matic Valves, Inc., Cedar Grove, N.J.

Screening is made simple with this combined system
This 3-in-1 system combines a Vibroscreen vibratory screener (photo), a batch hopper and an integral feed-control device that regulates the flow of material into the screener. The feed-control device consists of a circular disc positioned below the flexible connector at the screener’s inlet, perpendicular to the flow of material. The diameter of the disc is smaller than the inside diameter of the inlet, forming an annular gap through which material can pass. Because the disc vibrates with the screener lid to which it is affixed, the flow of material through the gap remains uniform. Interchangeable discs in a range of diameters are provided to achieve various feedrates. Feed-control devices for the Vibroscreen units range in diameter from 18 to 40 in. and are offered with single- or multiple-screening decks that separate particles in one to five sizes from 2 in. to 500 mesh (25 µm). — Kason Corp., Millburn, N.J.
