Safety and Kelly Valves

TIW is the original designer and manufacturer of ball type Safety and Kelly valves. 

Over the years, on rigs around the world, Safety and Kelly valves became known simply as the TIW valve. Our strict adherence to API specifications and our own quality requirements ensures our customers that TIW valves are the highest quality valves in the market.

The Ball-Type Safety Valve provides a quick, sure shutoff in the drill string that can repay the cost of the valve quickly as kick protection. 

The TIW Kelly Valve is designed to hold pressure in either direction and can be used as a Drill Stem Safety Valve or as either an Upper or Lower Kelly Cock. 

It has an exclusive corrugated spring to ensure a positive seal. Standard pressure rating is 10,000-pound test, but higher ratings are available. The ball is stainless steel and closes easily.The full-bore Kelly valve will not interfere with running tools like core barrels or survey instruments. 

TIW also offers the Ball-Type Kelly Valve for H2S services, meeting all NACE standards. Kelly Valves are available in API Type I and Type II.
