Product Features

Pilot-operated Structure: The valve applies a large & small spool pilot-operated design, incorporating a pressure-balanced pilot-operated spool for enhanced performance.
Compact & Efficient Design: Features a small volume and compact structure, optimizing space and performance.
Superior Sealing Effect: Provides excellent sealing, ensuring no visible leakage (ANSI V standard), and is essential for applications requiring zero leakage and full sealing.
Superior Cutting Ability: Capable of managing high-temperature and high-pressure differential conditions, offering effective flow control.
Wide Range of Applications: Ideal for various automation systems and harsh conditions where precise control is necessary.
Enhanced Durability: Designed for long service life, even under demanding conditions.
Cavitation Resistance: In high-pressure differential environments, the valve prevents cavitation and erosion of the spool and seat, even with micro-leakage in the seat.
Efficient Sealing at Reduced Actuator Size: Unlike traditional valves that increase actuator size to improve sealing, this pilot-operated single-seat valve minimizes actuator dimensions while enhancing sealing, leveraging the imbalance force from pressure differences.
