The NIBCO® grooved end NSF Certified butterfly valve provides bubble-tight shutoff at 300 PSI. Grooved ends are compatible with IPS pipe. The valve is ideal in grooved steel pipe systems for commercial and some light industrial process applications, including HVAC, in addition to hot and cold potable water.The NIBCO® ductile iron butterfly valve provides ease of operation with quarter-turn (90 degrees) open to close. The valve features an EPDM encapsulated ductile iron disc. The internal stem/disc splined drive design eliminates the need for pins or bolts that may create leak paths or turbulence in the waterway.
