THE QUALITY IS BUILT IN
Strong, corrosion-resistant stainless steel valve balls. Heavier wall steel valve bodies made from tempered steel. Crystin uses only the best, most durable materials in each kelly valve. Every ball, stem and seat delivers corrosion protection you can rely on for long life and dependable service.

NO ONE BUILDS A STRONGER,
BETTER VALVE
Every kelly valve from Crystin has been tested in open and closed positions to 10,000# psi, and high-pressure valves to 15,000# psi. Pressure tests are run above and below the valve, to insure its reliability in the field, and assurance counter-balancing (equalizing) is obtainable to the highest pressure the valve is rated to.

A complete line of kelly valve parts - springs, balls, seats, etc., - are available in stock, and are interchangeable with other valves. Major and minor repair kits are also kept in inventory.
