YSIQ(D)30 Intelligent Cage-Type Control Valve

Straight-through S-shaped body design, low flow resistance, high flow capacity.

Sleeve-guided balanced plug improves valve stability.

The sleeve is tightly connected to the valve body, effectively enhancing the valve's sealing class and stability.

Extremely easy to use and maintain.

The sleeve is connected to the valve body in a compression manner, effectively enhancing the valve’s sealing class and stability, while being exceptionally convenient for use and maintenance, significantly improving the overall performance of the control valve.

How the Cage-Guided Design Works

The YSIQ(D)30 is an intelligent cage-type control valve with a sleeve-guided balanced plug. The sleeve-guided arrangement is intended to support plug stability, while the modular construction allows the flow characteristic and pressure-temperature configuration to be reviewed for the operating case.

The product page lists equal-percentage and linear flow characteristics, a 50:1 rangeability and Class III, Class IV or Class V leakage options for the applicable pilot type. Confirm the selected trim, leakage class and temperature configuration before quotation.

Design and Maintenance Features

• Sleeve-guided balanced plug: The sleeve-guided plug supports stability and provides a distinct product position from the top-guided YSIQ(D)10.
• Dual metal sealing: The product description identifies a dual-metal-sealing configuration. Confirm the applicable seat materials, temperature range and leakage class for the order.
• S-shaped flow path: The straight-through body design is intended to provide low flow resistance and high flow capacity.
• Compressed sleeve-to-body connection: The product page identifies a compression connection intended to support sealing class, stability and maintenance.
• Modular construction: The body and trim arrangement should be matched with the required flow characteristic, pressure class, temperature and actuator.

Selection Review for High Temperature or High Differential Pressure Service

For high-temperature or high-differential-pressure service, the valve should be reviewed as a complete assembly. Confirm the following before final selection:

• Flow rate and required Cv/Kv for all operating cases.
• Upstream and downstream pressure, pressure drop and pressure-reduction stages.
• Fluid phase, temperature, viscosity, solids and corrosive components.
• Required flow characteristic and controllable operating range.
• Cavitation, flashing, noise, vibration and trim-erosion review where applicable.
• Seat leakage class, actuator force and fail action.
• Bonnet, bellows, cooling-fin or cryogenic configuration required by the temperature range.
• Testing, inspection, material certificates and project standards.

The page should not claim that every YSIQ(D)30 configuration is anti-cavitation, low-noise or suitable for every severe-service duty unless the corresponding trim and test evidence are available.
