■ Overview

HLAS small caliber single seat angle regulating valve is one of the CV3000 series products. The HLAS small caliber single seat angle regulating valve core adopts an upward guide structure, which is compact in valve structure, has low pressure drop loss, large flow rate, wide adjustable range, and high precision in flow characteristics. The leakage rate of the regulating valve complies with ANSI B16.104 standard. The regulating valve is equipped with a multi spring thin film actuator, which has a compact structure and high output force. This product complies with the GB/T4213-92 standard.
