KSB announced the release of the ZTS Gate Valve with Pressure Seal Bonnet. Modern sustainability demands require power plants to increase efficiency and reduce CO2 emissions. With its hammer-forged steel body, the valve can handle water, steam, gas, oil, and other non-aggressive fluids, even at temperatures in excess of 1000°F. The valve’s efficiency and durability make it perfect for industrial settings, power stations, and process-engineering systems.
The ZTS utilizes a fine-grained, homogenous hammer-forged body design that can withstand some of the highest pressure (up to 8700 psi) and temperature (up to 1200°F) ratings. This forged body is nearly invulnerable to pores and pitting and contains a weldable, strong surface. In comparison to similar cast steel designs, the ZTS’ robust design in unmatched.
For internal sealing, the ZTS is equipped with a movable, double-wedge design. The valve’s forged steel double-wedge holder prevents the wedge halves from additional actuating moments and additional loads on the seat/disc interface. The result is flexible and precise wedge movement with reliable operation.
These parallel discs are supported by replaceable disc springs with a parallel pin. This design presses the parallel discs against the valve body seats to help protect against temperature and pressure fluctuations.
Sealing off process fluid from the atmosphere is a vital aspect of efficient gate valves. The ZTS features a confined graphite gland that prevents packing from creeping into the clearance between the valve’s stem and body.
