◆ Product Introduction

DHCUElectric unbalanced cage type regulating valve The valve core adopts an upward guiding structure, which is compact in structure and has aSThe streamlined channel reduces pressure drop loss, increases flow rate, has a wide adjustable range, and high accuracy in flow characteristics, which is in line withIEC534-1-1976Standard. The leakage of the regulating valve meets the requirementsANSI B16.104Standard. The product complies withGB/T4213-92、JB/T7387-94.
