◆ Product Introduction

DHLC electric small-diameter cage type single seat regulating valve is suitable for high-pressure applications where the liquid pressure difference exceeds 3MPa. It is a high-performance regulating valve with a sturdy valve core guide and sleeve to prevent liquid flash evaporation and cavitation. The electric small-diameter cage type single seat regulating valve has a compact structure and an S-shaped channel, which reduces pressure drop loss, increases flow rate, and has a wide adjustable range. The leakage of the electric control valve meets the ANSI Bl6.104 standard. Electric small-diameter cage type single seat regulating valve complies with GB/T4213-92 JB/T7387-94。
