Applications for Bellows Seal Globe Valves

2 Way Plug Valve
FRP–2 Way Plug Valve
3 Way Plug Valve
FRP–3 Way Plug Valve

cunico's Full Round Port (FRP) self-lubricated plug valve is designed exclusively for sanitary system service. Our drip tight plug valve is highly corrosion resistant to sewage and seawater. The FRP plug valve operates freely under full line pressure and low breakaway-torque permits hand operators.

Advantages of FRP Plug Valves:
  • Low Breakaway-Torque
  • Non-Clogging
  • No-Lubrication
  • Operated by Lever, Handwheel, Actuator
  • Operates freely under Full Line Pressure
  • Highly Corrosion-Resistant to Sewage / Seawater
  • Drip Tight
  • CHT (Chemical holding tanks) application(s)
Extended Operating Life of Plug Valves
Example - In February of 2002, NGNN started the RCOH of CVN-69-Eisenhower, and replaced cunico plug valves originally installed in 1988, after 14 years of service, with new cunico plug valves.
