Product Features

Y Pattern (Oblique) Design: Angled seat and stem design significantly reduces flow resistance (lower pressure drop) compared to standard globe valves, ideal for applications requiring continuous flow with throttling capability.
Bellows Seal: Fully welded stainless steel bellows provides a hermetic seal, eliminating fugitive emissions and ensuring zero stem leakage—critical for steam, thermal oil, and hazardous media applications.
Pneumatic Actuation: Enables remote, automated operation for on-off or modulating control, improving system efficiency and safety.
Fail-Safe Operation (Spring Return): Spring-return actuators ensure valve returns to a safe position (fail-open or fail-closed) upon loss of air supply, providing critical safety protection.
Raised Face Flanged Ends: Standard RF flanges ensure reliable, leak-free connections compatible with ASME or EN piping systems.
PN16 Pressure Rating: Suitable for low to medium pressure applications commonly found in steam distribution, HVAC, and industrial processing.
Hard-Faced Trim (Optional): Stellite hard-facing on seat and disc surfaces provides excellent wear resistance and tight shut-off for demanding services.
ISO 5211 Mounting Pad: Standardized mounting interface ensures easy actuator installation, alignment, and maintenance.
Accessories Ready: Designed to accommodate solenoid valves, positioners, limit switches, and air filter regulators for complete automation packages.

Remarks:

Material Selection: Specify body material based on media:

WCB: Water, oil, steam, non-corrosive services
CF8 (304): Mildly corrosive services
CF8M (316): Highly corrosive services, chlorides, and marine applications

Actuator Selection: Specify actuation mode:

Spring Return (Fail Closed): Air to open, spring to close
Spring Return (Fail Open): Air to close, spring to open
Double Acting: No fail-safe, requires air supply to both open and close

Control Type: Specify whether the valve is for on-off service (solenoid valve control) or modulating service (positioner with 4–20 mA signal).
부속품: Specify required accessories for complete automation:

Solenoid valve (voltage: 24VDC, 110VAC, 220VAC, etc.)
Positioner (analog 4–20 mA / digital / HART / Profibus)
Limit switches (mechanical / proximity / inductive)
Air filter regulator (with pressure gauge)

Fugitive Emissions: For applications with strict environmental compliance, specify ISO 15848-1 certification.
For specific dimensional data, actuator sizing, torque requirements, and wiring diagrams, please refer to the official certified drawings and actuator assembly documentation from the manufacturer.
