Rated to 300 degF [149 degC]

Manage risks reliably, with slickline versatility

A-series velocity valves are engineered to prevent wells from overproducing or blowing out if surface controls malfunction or become damaged. These valves are operated with differential pressure and set to close at a predetermined flow rate. You can change the rate by changing the spring, using spring spacers, or varying the inside diameter of the choke bean.

The valve is designed for reliability in sweet to moderately corrosive environments.

A-series velocity valves are available in a variety of materials. They feature a premium flapper mechanism with full metal-to-metal sealing plus a secondary soft seat. They are designed to meet or exceed API and ISO leakage acceptance criteria.
