The Calvary C1-EX Expanding gate valve is designed for critical service in the pipeline oil & natural gas wellhead applications along with corrosive or erosive services throughout the energy industry in ANSI 150 to 1500 Class operating pressures.
All model C1-EX Expanding gate valves are manufactured per the latest edition of API 6D requirements. They 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 life of the valve. This provides a superior valve in demanding applications including those requiring zero-leakage in Double Block and Bleed service. The valves are designed for easy in line service to be performed through the top entry access. These features resulting from the rugged design make the C1-EX suitable for both common and more difficult applications throughout the energy industry.
