Balanced Cage Design

–

Pressure-balanced plug with piston rings reduces unbalanced forces, allowing smaller actuator and higher shut-off differential pressure . Cage provides guiding and flow characterization.

Seat Leakage Class

ANSI/FCI 70-2 Class IV (0.01% of rated Cv)

Optional: Class V (0.0005 ml/min/inch seat dia. per psi diff.)

Basic Error

±2.0% (with 3610L actuator)

Hysteresis (Dead Band)

≤ 1.0%

Repeatability

≤ 0.5%

Shell Test Pressure

1.5 x Rated Pressure

Seat Test Pressure

1.1 x Rated Pressure

Maximum Allowable Differential Pressure

Up to 10 MPa (depending on size and trim selection)

Noise Reduction

Cage with multi-hole / reduced noise trim optional

Balanced Cage-Guided Design

Reduces dynamic and unbalanced forces, enabling higher shut-off pressures and smaller actuator selection . Cage provides precise guiding, reducing vibration and noise.

Equal Percentage Flow Characteristic

Provides excellent control at low flow rates and stable gain throughout operating range. Ideal for pressure, temperature, and level control loops where system pressure drop varies .

Integrated Electric Actuator

Built-in servo amplifier accepts direct 4-20mA control signal; no external positioner required .

Explosion-Proof Certification

Exd IIB T4 certified for hazardous locations (Zone 1, Zone 2) . Suitable for oil & gas, chemical, and petrochemical plants.

Live-Loaded Packing (Optional)

Belleville springs maintain constant packing force, compensating for wear and thermal cycles; reduces fugitive emissions.

Interchangeable Trim

Cage, seat, and plug can be replaced without removing valve body from pipeline (top-entry access via bonnet).
