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