CV3000-KHSC Explosion proof electric cage type single seat regulating valveDetailed product description：

Detailed introduction:
The CV3000-KHSC electric cage type single seat regulating valve is suitable for situations where high pressure differentials are 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 has a compact structure with S-shaped channels, which 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 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.

DHSC explosion-proof electric cage type single seat regulating valve complies with GB/T4213-92 and VDS4006-92 standards.
