HCB Cage type double seat regulating valveDetailed product description：

summary:

The HCB cage type double seat regulating valve is a pressure balanced regulating valve, with an S-shaped fluid channel inside the valve and a guiding wing to improve the smooth flow of fluid around the sleeve. Its advantages are low pressure drop loss, high flow rate, and wide adjustable range. The flow characteristic curve has high accuracy and good dynamic stability. Low noise, minimal cavitation and corrosion, good dynamic stability of regulating valve, low noise, air defense, suitable for controlling high-pressure differential fluids at various temperatures. Equipped with LHA multi spring thin film actuator or electric actuator, it has a compact structure and high output force. The product complies with GB/T4213-92.
