High Pressure, High Temperature Valves

In 1962, Mr. Chester Siver completed designs for a revolutionary line of high pressure forged steel valves. Hamilton Standard, division of United Technology, was asked to use their then new Electron Beam Welding technology for joining of parts into valves for subassemblies. Hamilton Standard became intrigued with the valve as an ideal application of the Electron Beam Welding technique and negotiated a contract for rights to manufacture and sell the valve and for Mr. Siver to serve as the manager of the valve project. The date was August 8, 1962. 

The first CLAMPSEAL® valves were marketed by Hamilton Standard in 1964. The growing demand for aerospace products forced. Hamilton Standard into a decision to abandon its industrial products projects and CLAMPSEAL® valve production ceased in April of 1965. One year later under the terms of their contract all rights to the valve reverted to Mr. Siver. 

Conval was incorporated in 1967 in Somers, Connecticut and has never looked back. From very modest sales in the early years, the company was able, nevertheless, to always show growth. It has steadily expanded its product line to where it now includes: Y, Angle, and T-pattern Globe valves and Gate valves in 900 - 4500 lbs. series and 1/2" - 4" sizes; Whisperjets; Quadflow; Multiple Orifice Blowdown valves; Cryogenic and Bellows Seal valves. Today Conval is the premier manufacturer of high quality, high pressure forged steel valves in the world. Significant areas of growth for Conval include sales in Southeast Asia and developing third world countries. 

The story of Conval is one of commitment to producing valves of superior design, out of superior materials and unsurpassed workmanship. The company is a local success story for a group of dedicated New England Yankees who don't believe that they can't compete in today's market.  Mr. Siver died in his sleep in 2003 at age 90.  Conval continues as a family owned business through his son Frank.

The CLAMPSEAL® valve represents the proverbial better mouse trap. Ingeniously simple, the basic valve is comprised of only nine components. The valves are lightweight and at the same time incredibly tough and durable. Perhaps most significant of many advantages, the CLAMPSEAL® valve is much easier to repair than anything else on the market. The bad old days of use it up and throw it out have been replaced with a desire for quality, renewability and longevity. Low first cost is not as important as low cost over the serviceable life of valves. Conval has benefited from this change in attitude and is still growing. 

The future holds much promise. Conval is developing new products to meet the challenging conditions imposed by industry. Conval continues with new leadership and innovation from a new generation of engineers
