Industrial Regulators

PRESSURE REDUCING REGULATORS

The Model 345 is a heavy-duty high- pressure regulator commonly found in hydraulic or gaseous service.

MODEL 8310LP/8310HP

MODEL 345

Cashco has been a technological pioneer in the regulator industry since 1914. The regulators are designed to perform and built to last with the highest Cv and regulation accuracy available per valve size. They also offer the highest rangeability of any regulator in the industry. Cashco regulators cover a wide range of compatible fluid applications including: water, steam, all industrial gases, acids, cryogenic fluids, PRESSURE REDUCING REGULATORS

The Model 8310LP and the Model 8310HP are some of the highest-capacity pressure reducing regulators we manufacture. Their balanced plug design and double-port construction yields outstanding performance even at very low pressure drops. Diaphragms are isolated from fluid velocity effects. Applications include a wide variety of fluids.

The Model 345 utilizes a piston design to handle high pressures. With optional nylon or

TFE seats, it can control downstream pressures between 50 and 3000 psig with inlet pressures as

high as 4000 psig. A metal-seated version with an unbalanced trim design is also available. The Model 345 is used primarily as a first-stage letdown valve on high-pressure applications. It is not designed to be used in steam applications.

The DA1 is an excellent pressure reducing regulator for all fluid types. Whether it is GOX or a viscous fluid, the Model DA1 is able to provide constant and accurate control through the necessary range of flow of your application. The regulator features a high flow design with balanced trim as a standard. The balanced trim allows rangeability up to 1000:1 for varying flows with very little change in set pressure. Due to

Model CG-PL is a pressure-loaded, flow-to-open, direct-action, loading-type pilot regulator. Used in gaseous service only for pressure reducing or backpressure applications. Pressure-loading design increases sensitivity by eliminating the resultant “droop effect” range spring. May be loaded with process or auxiliary gas.
