Threaded Flow-Adjustment Valves with Garden Hose Outlet
- For Use With: Oil, Water
- Valve Type: Globe
These valves have an NPT inlet and a GHT outlet for attaching garden hose. They gradually open and close with multiple turns of the wheel handle to adjust and regulate flow. All have a nonrising stem that stays in the same position whether the valve is open or closed.
Lockouts (sold separately) thread over the valve outlet and lock in place with a padlock (not included) to prevent unauthorized water use.

Sanitary Sampling Valves
- Valve Type: Stop Cock
- For Use With: Food, Beverage
- Specifications Met: FDA Compliant 21 CFR 177.2600, FDA Compliant 21 CFR 177.1550
Take liquid samples in sanitary environments—these sampling valves have a hygienic design, so they’re commonly used in breweries and wineries. With a body made of 316 stainless steel and a PTFE plastic seat, they resist the high temperatures and harsh chemicals of clean-in-place (CIP) processes. These valves have an extremely smooth surface, leaving no space for bacteria to grow. Quick-clamp connections, also known as tri-clamp fittings, are easily taken apart for regular cleaning. These valves are self-draining, so previous samples and cleaning chemicals won’t contaminate future samples. Both the seat and the silicone O-ring comply with FDA standards for direct contact with food and beverage.
To take samples, turn the thumb screw to open valves. Hang a bucket for sample collection from the bucket groove. Valves also have a leak detection port that will release a small amount of liquid to let you know when it’s time to replace all the valve seals.
Valves with a bent spout have a tab for connecting carbon dioxide testing devices. They’re often used for carbonated beverages. They shouldn’t be used with liquids that have solids in them, such as the grape skins or seeds in wine, as those can get caught in the outlet.

Swivel On/Off Valves with Garden Hose Threads
- Valve Type: Ball
- For Use With: Water
- Temperature Range: 35° to 120° F
Keep fluids flowing—these valves twist and turn to prevent your hose from kinking. They connect to your faucet and swivel 360°, which makes it less likely your hose will kink when you move it side to side. Their lever handle is easy to turn, and lets you know if the valve is open or closed at a glance.
Zinc valves have good corrosion resistance. A plastic coating protects your hands by keeping the valve’s surface from getting too hot or cold.
Brass valves are more durable and corrosion resistant than zinc valves.
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.
Add a kink absorber for additional protection to your hose. Connected between the valve and the hose, they prevent kinking from sharp up and down movements.
