Threaded On/Off Valves with Gauge Port
- Valve Type: Ball
- For Use With: Air, Water
- Seal Material: Fluoroelastomer Rubber
- Specifications Met: C-UL Listed, CSA Certified, CSA-US Certified, UL Listed
Attach a pressure gauge to the side port on these valves. The side port can also be used to drain and divert liquid. Valves are full port, so they do not restrict flow.
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.

Lockable On/Off Inline Hydraulic Valves
(Padlock Not Included)
Lock the handle using a padlock. When unlocked, a quarter turn of the handle starts and stops flow. Valves are full port, so they do not restrict flow.
UN/UNF (SAE Straight) thread connections have straight threads and are also known as O-ring Boss fittings.
