Start or stop flow with the flip of a toggle switch or the push of a button. These valves are often used in testing and sampling applications where you need to dispense a small amount of liquid. They fit through a cutout, so the body of the valve stays safe inside your instrumentation panel.

Nickel-plated brass valves resist corrosion better than plain brass valves. 316 stainless steel valves stand up to corrosion better than both plain and nickel-plated brass valves.

Manual-return valves stay open until you flip the toggle off. Since they don't need to be held open, they’re often used to dispense larger samples than spring-return valves. It’s also easy to check if these valves are open or not based on the toggle’s position. Spring-return valves automatically close when you release the toggle or push button. They’re ideal for intermittent use and precise flow control to prevent spills.

Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Push a button or flip a toggle switch to start or stop flow. Often used in testing and sampling, these valves are useful when you need to dispense a small amount of liquid.

Nickel-plated brass valves resist corrosion better than plain brass valves.

Push-button valves automatically open or close when you take your finger off the button. They’re ideal for intermittent use and applications where you want to monitor flow closely to avoid spills. The button is colored to make it easy to tell different valves apart. Normally open valves close when you push their button. Normally closed valves open when you push their button.

Toggle valves stay open until you flip them closed. Since they don't need to be held open, they’re often used to dispense larger samples than push-button valves. You can see if these valves are open or not based on the toggle's position.

Valves with an exhaust port release extra air or liquid when they close. When these valves open, the exhaust port closes.

Flip the toggle to quickly turn these valves on and off. All have threads and a hex nut below the handle for installation in instrument panels. For extra gripping power and a strong seal, they have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

Take samples in sanitary environments—these tube fittings won’t contaminate your lines or force you to pause them. Made of 316L stainless steel, they’ll stand up to harsh cleaners and sanitizers without corroding. They also have polished internal surfaces, minimizing the space where bacteria could grow. With quick-clamp connections, they are easy to take apart for cleaning or reconfiguring your line. All are 3-A certified to meet sanitary design standards, so they’re often used in food and beverage, pharmaceutical, and biotech applications.

All fittings require pierceable lids (sold separately) to draw samples through a hypodermic needle. Each lid is good for seven samples, and each sample leaves a hole mark, so you know when it’s time to unscrew the nut on the tube fitting and swap in a new lid. To help prevent dust and moisture from accumulating on the lid, all tube fittings have a dust cover. These lids are FDA compliant, so they keep contaminants from entering your line and also are approved for direct contact with food if they break off and fall in. Manufactured free of contaminants and allergens, all are BPA-, latex-, and phthalate-free. They’re also TSE/BSE compliant, meaning they’ve never come into contact with any animal products.

Pair these tube fittings with liquid samplers for a sample. They use gravity to draw out liquid through the needle directly into the bag.
