(all non-shock ratings)

Features

Bi-directional shut-off valves.
Compact design.
Self-aligning gland box.
316 S/S valve body construction for superior corrosion resistance.
One piece integral cast body, chest and lugs.
Polyurethane liner bonded to the valve body.
Wide range of valve sizes available.
PTFE coated gate to provide a non-stick, low co-efficient of friction to lower operating force.
Complies with MSS SP-81 face-to-face dimensions.
High flow rates with low pressure drops.
All valves are pressure tested to MSS SP-81.
