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 sub-assemblies.
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 CLAMPSEALŪ
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 CLAMPSEALŪ 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,
it has steadily expanded its product line
to where it now includes: Y,
Angle, and T-pattem 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.
