The Caliber® well service valve and seat were designed for higher temperatures and pressures seen in today’s well service industry. The valves use our proprietary blend of urethane to ensure longer life.

We manufacture and stock a wide variety of standard service valves and seats, including: Full-open design for maximum mud flow (Novatech, G2, and Roughneck compatible designs available) Web design available with 3-web or 4-web designs High temperature versions for up to 300 F

The Caliber® 4-Web valve and seat are designed for today’s high pressure drilling conditions. Each piece is forged from a single piece of proprietary, high-strength alloy steel and is case hardened to precisely controlled levels. We have molded our high temperature, high impact resistant urethane to the valve body in order to eliminate the existing gap you will find on replaceable insert type valves. The 4-web design holds the valve weight to a minimum by increasing the load bearing area. In order to allow quick flushing of solid matter we use a steep angle that also...

The Caliber® XS valve seat was designed for today’s high pressure, extreme service drilling conditions. The wide valve seat surface area increases service life. Utilizing case hardened, high strength alloy steel, the Caliber XS seat was designed and field proven for 7500 psi applications. Full open design evenly distributes load on model seat deck No lower lip; standoff can be easily measured Open seat design allows for removal of bottom seat on valve-over-valve design...

Caliber® XV-400 valves are designed to take the constant pounding of full 7500 psi pumps in extreme pressure, extreme service situations. They are forged from a single piece of proprietary, high-strength alloy steel and are case-hardened to precisely controlled levels. An impact and high temperature resistant urethane seal is molded in place for maximum performance under abrasive and extreme conditions. Each part is individually inspected to ensure 100% performance and satisfaction. Good in high temperature applications up to 300°F ...

Designed to operate in mild to intermediate conditions, the Patriot™ VXT Valve is an economical alternative to higher temp/harsh duty options. The VXT works best in oil based mud applications with temperatures below 280°F. Single body forged insert provides excellent impact resistance Bonded, high temperature urethane seal Excellent abrasion resistance including resistance to LCM material 7500 psi pressure rating Works well...

The Patriot™ Harsh Duty Valve is a bonded urethane valve that will hold up to the most hostile drilling environment, withstanding high pressure, high temperature and high solids. Superior performance, long run life, excellent abrasion resistance and sealing surface coupled with the highest rated chemically resistant urethane make the Patriot™ Harsh Duty Valve an excellent choice for any drilling application. All Patriot™ parts are manufactured in-house and not sub contracted Unique urethane bonding anchor ...
