Electric single-seat cage control valve

OMAT Electric Single Seat Cage Control ValveOverview

The OMAT Electric Single Seat Cage Control Valve from Huizhou, Guangdong Province is suitable for high-pressure differential applications prone to flashing and cavitation. It is a high-performance single-seat control valve with a sturdy cage that protects the valve body from damage caused by flashing and cavitation. The valve features a compact structure and an S-shaped streamlined flow path, resulting in low-pressure drop loss, high flow capacity, and a wide adjustable range. The large guiding area of the valve plug ensures excellent anti-vibration performance.

● Top-mounted double-guided single-seat valve with a compact structure, sensitive operation, fewer components, and easy maintenance;
● Robust valve stem and integrated valve plug capable of withstanding high loads without detachment;
● Self-aligning snap-in seat is easy to remove and achieves tight shut-off sealing without grinding;
● The valve body is designed with an equal cross-section, low-flow resistance channel based on fluid dynamics principles, resulting in low-pressure drop loss, high capacity, and a 30% increase in rated flow compared to the system;
● The valve plug and seat cage are available in standard and severe service types (cavitation elimination, noise reduction, etc.), offering longer service life, higher cavitation resistance, and noise reduction performance. Simply replace the seat cage to meet different operational needs;
● Valve closure is achieved through fluid pressure, spring reaction force, and cylinder thrust, providing high resistance to fluid pressure differentials and ensuring tighter shut-off;
● Double-guided, dual-structure design reduces the possibility of external packing leakage;
● This series of control valves can be installed for flow-to-open or flow-to-close operation.

OMAT Electric Single Seat Cage Control ValveFeatures

1. Wide adjustable range with an inherent adjustable ratio of 50; flow characteristics include linear and equal percentage.
2. The regulating shut-off type uses a soft-seal structure valve plug, achieving Class VI leakage standards (zero leakage).
3. The servo amplifier employs deep dynamic negative feedback to improve automatic adjustment accuracy.
4. Various types of electric actuators are available, compatible with 4~20mA.DC or 0~10mA.DC signals.
5. The bellows-sealed control valve provides complete sealing for the moving valve stem, preventing fluid leakage.
6. The electronic electric control valve can directly control the valve opening via current signal without requiring a servo amplifier.
