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.

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.

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.

Breakaway Hose Couplings for Chemicals and Petroleum
Minimize chemical and petroleum spills during accidental disconnects, such as a driver pulling away during loading. These couplings have a shut-off valve on each half to stop flow when they’re separated. Attach one end to your hose and the other to a supply pipe or a second hose.
Aluminum couplings are lightweight and have good corrosion resistance.
316 stainless steel couplings have excellent corrosion resistance.
2 NPT and 3 NPT couplings have bolts designed to break before your hose does. They can be repaired with replacement bolt kits and replacement seal kits (both sold separately).

Minimal-Spill Push-and-Turn Hose Couplings for Chemicals
Quickly connect and disconnect hose lines used with a variety of chemicals, from adhesives to isopropyl alcohol and ink. Any part of these couplings that contacts fluid is made from 316 stainless steel, C-276 Hastelloy, PTFE, or fluoroelastomer to withstand the chemicals in your line. Tough enough to handle frequent use, these couplings are designed to be virtually spill free. Also known as dry disconnects and double-shut off couplings, both the plug and the socket have a shut-off valve that stops the flow of liquids when they’re separated. To connect, push the plug into the socket and lock with a quarter turn. The socket swivels, so you won’t have to twist your hose to attach the plug. It also has a rubber lip and large handles to prevent damage if it’s dropped.
A complete coupling consists of a plug and a socket (both sold separately). They’re compatible with MannTek, Avery Hardoll, Todo-matic, and other dry-disconnect couplings that meet NATO standard STANAG 3756.
Aluminum couplings are lighter in weight than stainless steel and have good corrosion resistance.
316 stainless steel couplings have excellent corrosion resistance.
