KGSHT
Born under the silos of heavy industry. Built to take 850 °C.
Zero dust emission. High pressure.
The full travel of the gate is confined inside the bonnet. The product stays in the valve: no dust is released to the atmosphere, on opening or on closing.
Every component selected for continuous duty.
The stuffing box and the gate-to-actuator linkage are adapted to withstand 850 °C: thermal decoupler between body and actuator, Thermiculite packing, high-temperature alloy scraper.
Pressed onto its seat, even loaded with powder.
Adjustable AISI 310 rollers guide the gate over its full travel. Operating force stays low, and the eccentricity presses the gate against the seat at the end of closing, whatever the product load above.
The valve always closes on a clean seat groove.
The flared body shape prevents any product from settling above the gate. No heap, no compaction: the gate cuts through the product and lands on a clear seat.
Integrated deflector, direct access to the seat.
The bolt-on flange carries the deflector that shields the sealing zone from the product flow. It gives access to the seat without dismantling the body and takes one of three sealing technologies: metal-to-metal, soft seals or dynamic metal.
In-line inspection and cleaning, no removal.
A hatch at the bottom of the body opens onto the gate groove. The operator checks the seat and clears deposits during a short stop, without taking the valve out of the line.
One valve, three body executions.
Material, sealing, coating and actuator are selected for your product and your temperature.
The body follows the process temperature.
Leakage classes II, III, IV or VI to ANSI/FCI 70-2. CE PED design, declaration 2014/68/EU module A.

Dimensions in mm, C = height with valve open and double-acting pneumatic cylinder. DN 50 and 80, other drillings and special executions: consult us. The 3D model shown is a DN 250.
- Tungsten carbide hardening — 0.2–0.5 mm spray, HRC 60–70, on deflector, gate and body outlet: the answer to severe abrasion.
- Lantern ring — stuffing box pressurised with air or inert gas.
- Belleville washers — dynamic stuffing-box sealing, permanent compensation of the tightening.
- Halar (ECTFE) coating — corrosion protection of wetted surfaces.
- Position sensors — inductive, 5/2 solenoid valve, filter-regulator.
Send us the product, the temperature and the DN. We size the valve.
