On/Off Valves with Grooved-End Fittings
- Valve Type: Ball
- For Use With: Air, Drinking Water, Oil, Water
- Seal Material: PTFE Plastic
- Specifications Met: NSF/ANSI 61, UL Classified, C-UL Classified
For quick and easy access to your line, these valves attach to pipe with a clamp (sold separately) that fits around their grooved ends. No heat or threading required. They’re also known as Victaulic valves. Made of ductile iron, these valves absorb vibration and resist cracking. They’re strong enough for systems with pressure changes and frequent starts and stops. All meet NSF/ANSI 61 for safe use with drinking water. They are full port, so they do not restrict flow. To prevent tampering, lock the handle with a padlock.
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.

Flow-Adjustment Valves with Grooved-End Fittings
- Valve Type: Butterfly
- For Use With: Water
- Specifications Met: MSS-SP-67
Commonly used in water service pipelines and HVAC systems, these valves have grooved ends that connect to pipe with a clamp (not included) for easy installation. Since there’s no heat or threading required, they provide quick access to your pipeline for routine maintenance. All gradually open and close to adjust and regulate flow. Valves have 10 flow-adjustment positions. Fix the lockable lever handle in place using a padlock (not included) with a shackle diameter up to 5/16”.
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.
