The FC SMLR Gate Valve is a field-proven design which provides reliability and interchangeability. The FC SMLR Gate Valve features a non-rising stem with a slab gate full bore through conduit design. Floating slab gate and seats, floating seat ring body bushing design to provide safe dependable service.
No special tools are needed to change gate and seat assembly. The stem pin protects the stem and internal parts from failure by shearing if the hand wheel is over torqued. One-piece gate helps to prevent line sediment from entering the body cavity and prevents pressure locks when the upstream pressure drops. A wide range of body and trim materials to meet various operating conditions.
FC SMLR Gate Valve Features
- Full bore thru-conduit design, promotes a longer working life
- Universal metal-to-metal sealing (Gate/Seat, Seat/Body)
- Working Pressure ratings from 2000 PSI to 20,000 PSI
- Bore size from 1-13/16" to 7-1/16"
- Seats can be lubricated from grease injection to minimize abrasion and torque
- Stem back seat's conical seal surface will push against bonnet, to allow Stem seal to be replaced when valve is still under pressure

Flanged FC SMLR Gate Valve Dimensions
- Flange face to face
- Bore centerline to bottom of valve
- Bore centerline to hand wheel top
