Adjustable Pressure-Relief Valves for Chemicals
- For Use With: Aluminum Chloride, Boric Acid
- Temperature Range: 40° to 140° F
Often used with catalysts, pH buffers, and electroplating solutions, these valves have a PVC body and an EPDM seal for excellent chemical resistance. They begin opening at the set pressure and fully open at about 10% over the set pressure. Valves begin closing as pressure drops and fully close when the system pressure is restored below the set pressure. Adjust the set pressure within the range. Valves have a port for attaching a pressure gauge.

Batch-Dispensing On/Off Valves
- For Use With: Beverage, Water, Kerosene, Bleach, Boric Acid, Deionized Water, Oil, Diesel Fuel, Food
Accurately and consistently dispense a specific amount of liquid—these actuated valves have a screen and buttons for programming batch size and calibration. They’ll automatically shut off once the set amount of liquid has been released. Their stainless steel body resists corrosion, so these valves can be used with harsh chemicals.

International Standard ISO Minimal-Spill
Quick-Disconnect Hose Couplings for Chemicals
To minimize fluid loss when connecting and disconnecting your line, these couplings have flat faces for a close fit and shut-off valves to stop the flow—they meet ISO 16028, which is an international standard for hose couplings. They’re also known as flush-face and double shut-off couplings. A complete coupling consists of a plug and socket (both sold separately). They connect and disconnect quickly, so use them if you need to access a line frequently. Made of 316 stainless steel, they have excellent corrosion resistance and withstand a variety of chemicals.
Plugs are also known as nipples.
Sockets are push-to-connect style. To connect, push the plug into the socket until you hear a click. To disconnect, slide the sleeve on the socket forward until the plug ejects. These sockets have an internal fluoroelastomer gasket that resists a wide range of chemicals, including benzene, butyl alcohol, and ethylene glycol.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size. Pressure ratings are given for static (constant) pressure conditions.
Warning: Never attempt to connect or disconnect couplings when operating at maximum pressure. Stop the flow before you disconnect the line.
