Conval is the premier manufacturer of high quality; high pressure forged steel valves in the world. The story of Conval is one of commitment to producing valves of superior design, out of superior materials and unsurpassed workmanship.
The CLAMPSEAL® valve (developed by Conval) 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.
Conval valves find a wide application of use especially in harsh industrial applications such as power plants, nuclear plants, oil and gas, military and many more.
Why CLAMPSEAL valves are Top performers in their class
Versatility
CLAMPSEAL® valves are tailored to the exact requirements of our customers. No other premium forged valve offers so many options. Conval provides three body styles in various pressure classes and three standard materials. Other materials are available to meet customer needs. The easy interchangeability of parts means that an entire plant installation can be supported with a very low parts inventory.
Performance
Our customers demand a valve
that does the job well with little attention. The CLAMPSEAL® valve is that
valve. Over 40 years of service in the most demanding applications have
established the CLAMPSEAL® valve as the top performer in its class and the
easiest to service.
Valve-Quality
The cost of plant shutdown time to repair or replace valves far exceeds the cost of equipment. Features such as electroless nickel plated finishand complete material traceability of all wetted parts and yoke instantly establish the quality of the CLAMPSEAL® valve. In fact, parts for valves built 40 years ago are interchangeable with parts built today.
Service
The CLAMPSEAL® valve is only part of the service program which attends to the continued needs of our valued customers. Conval representatives and regional managers are selected and trained to provide the necessary support to assure complete satisfaction.
