Cage type single seat regulating valve
Cage type single seat regulating valve
Product details
HSC cage type single seat regulating valve is a high-performance single seat regulating valve suitable for situations where high pressure difference causes flash evaporation and cavitation. The sturdy sleeve protects the valve body from damage caused by flash evaporation and cavitation. The valve body and fluid channel areSStreamlined design, low pressure drop loss, high flow rate, and wide adjustable range. The valve core has a large guiding area and good shock resistance. The regulating valve is equipped with a multi spring thin film actuator, which is compact in structure and has a large output force.
1HSCOverview of cage type single seat regulating valve
HSCCage type single seat regulating valveIt is a high-performance regulating valve, with a sturdy valve core guide and sleeve that can prevent liquid from flashing and cavitation. Compact structure, with presentationSThe streamlined channel reduces pressure drop loss, increases flow rate, and has a wide adjustable range.
The leakage rate of HSC cage type single seat regulating valve meets the requirementsANSI B16.104Standard. Adopting a multi spring pneumatic thin film actuator, it has a compact structure and high output force. The product complies withGB/T4213-92.
