■ overview
HCNLow noise cage type regulating valve isCV3000One of the series products.
HCNLow noise cage type regulating valve can reduce the noise of compressed fluid. To adapt to gas throttling diffusion and expansion, the sleeve is equipped with many symmetrical small holes to reduce pressure drop. The valve core adopts a pressure balanced structure. The fluid channel presentsSStreamlined and equipped with a guide vane to improve fluid balance around the sleeve, resulting in low pressure drop loss, high flow rate, and low noise. The leakage of the regulating valve meets the requirementsANSI B16.104Standard. 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 withGB/T4213-92Standard.
