Beswick Engineering Co., Inc. Datasheets for Gas Pressure Regulators

Gas pressure regulators reduce the pressure of a gas, as it passes through a cylinder or process line, to another piece of equipment. Regulators are not flow control devices. They are used to control delivery pressure only.

Product Name Notes
Back Pressure Regulator -- BPR Beswick Miniature Back pressure Regulator (BPR) is a normally closed valve that senses and responds to changes in upstream pressure. Like a relief valve, it will open to vent excess...
Single-Stage Piston Pressure Regulator -- PR Beswick miniature pressure regulators are designed to provide pressure regulation in a versatile miniature package. These regulators provide excellent pressure control despite their small size. Four different adjustment styles are...
Factory Preset Relief Valve -- RV2-1010-PP Miniature relief valve. Factory pre-set and secured 3-30 psig cracking pressure. Assembled, set, and 100% tested to order.
Ultra Miniature 3 Stage High Pressure Diaphragm Regulator -- PRD3HP The new PRD3HP series three-stage non-relieving high pressure diaphragm regulator sets an industry standard for both miniaturization and light weight. It weighs approximately 76 grams in brass. It accurately reduces...
Pressure Compensated Flow Control -- PCFC-1-1 The patented (Patent #6314980) Beswick pressure compensated flow control maintains a constant flow rate (adjustable 0-100 cc/min. of water) regardless of upstream or downstream pressure variations.
Pressure Compensated Flow Control Valve -- PCFCD-1N1 The PCFCD-1N1 is designed to maintain a constant flow rate, which the customer can adjust, regardless of upstream or downstream pressure variations. It works with both liquids (incompressible fluids) and...
Two-Stage Piston Pressure Regulator -- PR2 The PR2 series two stage piston style regulator is designed for applications requiring either a large differential between input and output pressures or a very precise pressure regulation. The regulator...
Single-Stage Diaphragm Pressure Regulator -- PRD The PRD-ANB-C-DEF regulator sets an industry standard for miniaturization as well as lightweight. It is an excellent choice for gas and pneumatic pressure...
Two-Stage Diaphragm Pressure Regulator -- PRD2 The PRD2-ANB-C-DEF two-stage non-relieving diaphragm regulator sets an industry standard for both miniaturization and light weight. It weighs approx. 50 grams in brass...
Manifold Mount Two-stage Diaphragm Pressure Regulator -- PRD28 The PRD28 manifold mount two-stage non-relieving diaphragm regulator sets an industry standard for both miniaturization and light weight. It weighs approximately 52 grams in brass. It accurately reduces high-pressure inputs...
Two-Stage Diaphragm Pressure Regulator -- PRD3 The PRD3 two-stage non-relieving diaphragm regulator improves upon our award winning PRD2 by incorporating larger ports and an improved valve design. It weighs approximately 66 grams in brass and stainless...
High Accuracy, Single Stage, Diaphragm Pressure Regulator -- PRDB The PRDB series regulator sets an industry standard for both miniaturization and light weight. It is similar to our PRD pressure regulator but with a patent pending valve mechanism, designed...
Sub Miniature Single Stage Diaphragm Pressure Regulator -- PRDB-18MM The PRDB-18MM series regulator is Beswick's smallest pressure regulator. It is designed with a patented pending valve mechanism designed to provided high precision/high seal reliability at low flows and at...
Manifold Mount, High Accuracy, 1 Stage Pressure Regulator -- PRDB8 The PRDB8 series regulator sets an industry standard for both miniaturization and light weight. It is a manifold mount version of our PRDB pressure regulator with a patent pending valve...
Miniature High Flow Diaphragm Pressure Regulator -- PRDHF The PRDHF high flow regulator sets an industry standard for miniaturization as well as lightweight. It is an excellent choice for gas and pneumatic pressure regulation applications, and is particularly...
Miniature High Flow Manifold Mount Pressure Regulator -- PRDHF8 The PRDHF8 manifold mount high flow regulator sets an industry standard for miniaturization as well as lightweight. It is an excellent choice for gas and pneumatic pressure regulation applications and...
Single Stage Piston Style Subminiature Pressure Regulator -- PR-MLS The Subminiature Pressure Regulator allows relatively precise pressure regulation in an envelope approximately the size of a miniature pneumatic fitting. The outside dimensions are exactly the same as Beswick's 10-32...
Miniature Diaphragm Vacuum Regulator -- VRD The VRD-ANB-CD vacuum regulator sets an industry standard for both miniaturization and light weight. It designed to control output vacuum from 0 psig to full...
