Pressure Regulators

Grainger pressure regulators are used to control the fluid flow while regulating the movement, direction and pressure of the medium passing through a system or pipeline. They have brass bodies that can withstand a maximum pressure of 300 psi and operate at a maximum temperature of 140 degrees F. They allow adjustable pressures ranging from 1 to 175 psi.

Parker P33R Series pressure regulators are used for for automatically stopping liquid or gas flow at a pressure set point to maintain safe pressure levels in valves & cylinders. These units feature robust and lightweight aluminium construction with balanced poppet design to offer quick response to the fluctuating downstream pressure. They are available in relieving / non relieving type configurations, where the former regulator allows excess pressure to escape until the system's pressure returns to normal. The latter, on the other hand, restricts the flow and traps it once the pressure increases and relies on other mechanisms to relieve extra pressure from the system.

Parker PR354 / PR364 Series pressure regulators are suitable for controlling the fluid or gas flow rate to a desired value in food beverage, pharma, oil & gas and industrial chemical processing applications. Their stainless steel construction withstands most corrosive environments and a large diaphragm assembly senses the downstream (inlet) pressure forcing the regulators to reduce the overall outlet pressure rate. They are further integrated with fluorocarbon seals offering high chemical and thermal stability and possess hydrophobic and antifouling properties. Choose from an array of these pressure regulators, available in 0 to 1.7, 0 to 4 and 0 to 1.8 bar pressure control ranges.

Parker P3LR Series pressure regulators are designed for accurate pressure regulation in low flow & space restricted applications. These pressure regulators are made from lightweight yet durable aluminium, and have an unbalanced poppet design. They can be easily installed via modular connectors and are ideal for the air & gas, automation, manufacturing, packaging & printing, and food & beverage industries. Parker P3LR pressure regulators have BSPP & NPT ports for connections and a pressure gauge with graduated readings (in both PSI and bar).

Parker P32H Series pressure regulators provide quick response and accurate pressure regulation in both front and rear ports. These units feature balanced poppet design that ensures stable pressure outputs even when supplied with variable pressure inputs. They can be easily mounted using a modular connector to other P32 / P33 Series global air preparation systems. These pressure regulators are ideal for cutting, machining, pick and place, factory automation, packaging and wrapping applications. Choose from an array of these compact common regulators, available in 1/4, 3/8 and 1/2 inch port sizes.

Parker P32R Series compact air pressure regulators are designed to regulate fluid supply in machining, manufacturing, industrial, automation, moulding, packaging, processing and food & beverage applications. These pressure regulators are made from lightweight & durable aluminium, and are suitable for pressure up to 250 PSI. They feature a balanced poppet valve for quick response & accurate regulation, and pressure gauge with graduated scale for readings. Choose from a wide range of air pressure regulators, available in 1/4, 3/8 and 1/2 inch port sizes.

Parker P31H Series mini common port air pressure regulators offer accurate pressure regulation in low flow & space restricted applications. They are ideal for valves, cylinders, tools & compressors in positioning, cutting, machining & packaging applications. These compact pressure regulators can easily be installed in low-flow and space-restricted areas owing to their robust & lightweight aluminium construction. They feature a balanced poppet for quick response & precise pressure delivery, and a pressure gauge (enclosed in an aluminium frame and toughened glass) for readings. Parker P31H Series pressure regulators have nitrile sealing for leakproof operation and manifold regulator for pressure control. Choose from a wide range of mini air pressure regulators, available in NPT, BSPP and BSPT connection ports.

Watts P60 Series miniature plastic water pressure regulators are ideal for regulating water pressure in commercial applications. These regulators feature a compact design with integrated cartridge-style valves that provide control of the water pressure. They have a bottom clean-out plug for easy maintenance. The internal metal components of these water pressure regulators are made of 300 Series stainless steel to resist corrosion when coming in contact with fluids. They can withstand pressures up to 300 psi.

Parker R230 Series pressure regulators are suitable for applications requiring high flow capacity and accurate process control. They are ideally used in gas mixing, valve operators, web tensioning, test panels, actuators, clutch and brake controls. These units have a balanced poppet valve that utilises a rolling diaphragm to ensure constant output pressure even when supplied with pressure variations. These pressure regulators further come with an aspirator tube that adjusts the air supply in accordance with flow velocity, thereby maintaining pressure in varying flow conditions. They facilitate on line maintenance, providing easy servicing without removing the air line.
