  • Introduction
  • Specifications
ZJHS-220、ZJHS-320 pneumatic diaphragm angular high-pressure adjusting valve used in high pressure or high pressure difference, severe cavitation, erosion conditions. Use multi-throttle type to share pressure difference, reduce cavitation, erosion and stream damage torsion, improve the using life of adjusting valve. Valve body is right angle, valve spool is single-guide structure, simple flow path, low resistance, especially suitable for high viscosity, suspended solids and granular media containing fluid to prevent coke, bonding, blocking
