The KVT as a specialist of valve engineering is now providing for customers the best product of good design of proper fluid flow control, the use of high quality materials, and the competitive price in the valve market.

        KVTs' unique SPL(Disc Spring Pack Loaded) disc trim unit comprises all of the operating parts of sliding discs. No wedging effect and much smaller contacting stresses on the seating mechanism. In high temperature service and high pressure service, the valve is never subjected to thermal binding since the SPL trim unit absorbs irregular thermal expansion due to the structural discontinuity of valve body.
        To avoid the seat wear, the disc and seat are hardfaced to keep a different hardness with Stellite #12 and Stellite #6 respectively. Remarkable different hardness be keeping to avoid a galling & its built-up effect on sliding metal surfaces. It results long life cycle life. The SPL centralized Inconel cone springs which distribute uniformly loading on both seats as well as compensating for irregular expansion of seats and seat wear. Also the precision guiding system in disc trim unit and disc unit to stem connection eliminate vibration(due to flow turbulence) of disc unit even the disc position in partly open. KVTs' SPL parallel slide gate valves can be throttling in any form of flowing condition.
