The Calvary C1-EX cast-body Expanding Wedge Through-Conduit gate valves are designed for
corrosive or erosive Pipeline service in oil and natural gas wellhead or other critical service
applications in ANSI 150 to 1500 Class operating pressures.

All Model C1-EX expanding gate valves are API 6D latest edition monogrammed equipment and are available in bore sizes ranging from 2” through 36”. The movement of the parallel expanding gate provides a bubble-tight mechanical seal to assure positive shut-off while reducing wear between the
sealing surfaces and extending the valve life. This provides a superior valve in demanding applications including those requiring provable zero-leakage in Double Block and Bleed service. The valves are designed for parts to be field repairable in line. These features resulting from the rugged design make it suitable for both common and more difficult applications throughout the energy industry.
