Detail Information
SPECIFICATIONS
Product Name: Eccentric Rotary Control Valve
Key Feature: Valve with Eccentric Plug
Sizes: DN25-DN450, 1 Inch - 18 Inch
Body material: Carbon Steel GP240GH(1.0619), ASTM A216 WCB, Stainless Steel GX5CrNiMo 19-11-2 (1.4408)
Plug and seat material: Stainless Steel
Pressure Rating: PN10-PN40, Class 150 LB - 300 LB
Operating temperature range: -46°C to + 450°C
Flow characteristics: linear
Flow coefficient Kvs: 3 – 3500 [m3.h-1]
Leakage class (IEC 60534-4): class IV, class VI
End Connection: Flanged, Sandwich
Type of Actuator: pneumatic diaphragm or piston (with handwheel), electric, electro-hydraulic, hydraulic
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.
