Packard Safety Valves are designed to either stab into the drill pipe or tubing at the rig floor or are used as part of the drill string to shut off a well kick. Use of these valves in the drill string enhances rig safety.

Valves are H2S Trim and available in API Spec 7-1 Class 1 or Class 2. All connections are available.

Features and Benefits

Easy Maintenance

The Packard two-piece safety valve offers the convenience of a two-piece body for easy maintenance. Its full bore also allows the unrestricted flow of drilling fluid; reducing wear on critical parts while providing unrestricted access for downhole tools.

Connection Flexibility

Safety valves can be provided with API or tubing connections. Special threads are available upon request.

Packard International's Safety Valves are built with enough length on each end to allow fully recutting the connections in the event of damage to the threads or shoulders where sealing takes place.

High and Low Pressure Sealing

High and low pressure sealing is assured by the Teflon and metal sealing system of the ball and seats. The ball and lower seat float while the upper seat is fixed in the body. This floating/fixed design aids in low pressure sealing and enables the operator to pressure balance the valve under full rated working pressure.
