◆ Product Introduction

DHPS electric high-pressure single seat regulating valve is a type of regulating valve with an upward guiding structure. The valve has a compact structure, low pressure drop loss, large flow rate, wide adjustable range, large guiding area of the valve core guiding part, and good anti vibration performance. The leakage rate of the regulating valve complies with ANSI Bl6.104 standard. The product complies with GB/T4213-92 JB/T7387-94 。
