KSB VALVE - BUTTERFLY VALVE KE

1. High operating reliability

• Patented secondary seal elements at the stem passages. The stem passages are reliably sealed even if surge pressures occur.

2. Valve stem in anti-blow out design (with shoulder) and steel bearings with reinforced PTFE lining.
3. Reliable long-term sealing at the flanged line connections

• The specially designed liner provides tight sealing at the flanged line connections, eliminating the need for an extra gasket. A back-up elastomer ring provides proper sealing even under vacuum conditions.

4. Absolutely reliable shut-off and sealing

• Tight sealing is ensured by compression between the liner‘s collar and the back-up liner between the stem and the body.
• The spherically machined valve disc and matching spherically moulded PFA liner ensure tight shut-off. The elastomer back-up liner guarantees reliable contact pressure.

5. Direct mounting of manual gearbox, electric or pneumatic actuator

• Top flange to ISO 5211 for a range of actuator options

6. Long service life, zero maintenance

• Unique AMRING sealing system

7. Compliance with the requirements of the chemical industry

• The weakest point of the stem is located outside the valve body and thus ensures safety for personnel and plant.
• Anti-static device (resistance < 10 Ohm)
• One-piece valve stem/disc
• Ground connection

8. Electrical continuity

• Elastic connection between stem and body
• Earth connection of the body
