Features:
1. One-Piece Valve Body: Cast with the bonnet, eliminating static or dynamic sealing except for the shaft sealing chamber.
2. No Detachment Effect: Ensures secure engagement between plug and seat.
3. Adjustable Kvs: Change Kvs values without replacing the plug or seat.
4. Easy Maintenance: Rotary, symmetrical plug can be easily replaced.
5. Elongated Bonnet: Allows for double shaft sealing, meeting "low emission" standards equivalent to TA-LUFT conditions.
6. Consistent Kvs Coefficients: Identical for both "hard" (metal-metal) and "soft" seats.
7. High Leak Resistance: Leakage class less than 0.01% Kvs for "hard" seats.
8. Uniform Flow Direction: Same for both "hard" and "soft" seats.
9. Accessible Valve-Actuator Connection: Can be rotated in 90° increments for flexibility.
10. Special Configurations Available: Options include heat jackets, erosion-proof designs, and adaptations for crystallizable media.
