■Structural characteristics and application scope
CV3000-HSCCage type single seat regulating valve is suitable for situations where high pressure difference is prone to flash evaporation and cavitation. It is a high-performance single seat regulating valve with a sturdy sleeve to protect the valve body from damage caused by flash evaporation and cavitation. The valve structure is compact and flexibleSThe streamlined channel reduces pressure drop loss, increases flow rate, and has a wide adjustable range. The valve core has a large guiding area and good vibration resistance. The leakage of the regulating valve meets the requirementsANSI B16.104Standard. The regulating valve is equipped with a multi spring thin film actuator, which has a compact structure and high output force. This product complies withGB/T4213-92.
