Frequently asked questions about Industrial valve sealing
What is industrial sealing in valve systems?
Industrial sealing in valve systems consists in ensuring fluid containment at equipment level, such as industrial valves, safety valves and taps. Drawing on its expertise in sealing solutions, LATTY develops technologies tailored to the most demanding applications to ensure the Reliability of installations, operator safety, and reduced fluid losses.
How do you choose a sealing solution for an industrial valve?
Selecting a sealing solution depends on many parameters: valve type, pressure, temperature, fluid nature, operating conditions, and regulatory requirements. Thanks to its technical expertise, LATTY supports its customers in selecting solutions suited to each application in order to optimize performance, equipment service life, and the Reliability of installations.
What are the advantages of LATTY gland packings?
LATTY gland packings are designed to provide high-performance sealing while reducing friction and valve operating torque. Made up of die-formed rings and anti-extrusion rings, they ensure excellent elastic recovery, effective sealing with low tightening, and simplified Maintenance, even under severe operating conditions.
