Inside BOP Valves

Inside BOP Valves

Protect your pumps, swive, standpipe, and from drill-string kicks with the inside B.O.P valve. Use the inside BOP valve anytime well kicks are expected, like when drilling through transitional zones. It is designed to be run thru most BOP stacks as an integral string part. The top vent allows fluids to partially flow by allowing safer and faster emergency stabbing.
Float Valve

Float Valves

We offer drill pipe float valves in both plunger (Models F, FA, FC), and flapper (Model G, GA, GB, GC, GBA, GCA) types. These float valves can be equipped for use in high-temperature environments.

Stem Guided Valve

Stem Guided Valves
& Web Valves

These stem guided valves and seats feature a wider metal to metal seal on the valve flange. The rigid seat cross-arms give positive sealing and greater strength. The serrated upper surface on the valve enhances the non-breathing seal between insert and valve body. The thick, strong, valve nut holds the insert tightly, thus reducing breathing and flex, lessening the chance of foreign matter getting between the insert and valve.

Bleed Ring

Bleed Rings

Bleed Rings provide an easy way to drain pipe, take samples, attach instruments, or even bleed a valve. Bleed rings can be used in a wide range of configurations. A bleed ring may be used to vent between two gate valves, they may have one or more outlets, and they may be installed with pressure guages. When used with a blind flange and valve, if your valve is leaking it allows you to relieve the pressure before you remove the flange.
