We introduce the new range of bellows seal valves

We are introducing at the next Valve World Exhibition the new range of JLX bellows seal valves focusing on offering an excellent quality at a competitive price.

The range of JLX bellows seal valves is basically designed to eliminate one of the most serious and frequent problems in steam and thermal fluid installations. This is the leakage through the gland, that can be the reason of unforeseen maintenance shutdowns, with the consequent cost due to loss of energy.

Long life and hermetic sealing

Standard JLX bellows seal valves are manufactured with carbon steel body & bonnet and double-layer bellows, despite we can manufacture other qualities and up to 12 multi-layer bellows. Normally used to achieve a perfect closure, even after years of inactivity, our bellows are capable of withstanding over 10,000 cycles without failure. These are generally used in thermal fluids installations, capable to resist temperatures up to 600 ° C. These are easy to repair and operate, having a semi-conical plug that offers added value as standard. Other obturator designs are available under request. You can request your stocks needs to our wide network of distributors.
