structural characteristics
Fully lined with fluorine technology, the valve body cavity, valve core, and valve stem surface are all covered with F4 fluoroplastic layer, only the fluoroplastic comes into contact with the medium, and has excellent corrosion resistance.
Pneumatic thin film actuator drive, stable output force, coupled with valve positioner can achieve flow regulation with 0.1% accuracy, high control precision.
Single seat valve core structure, reasonable flow channel design, linear or equal percentage flow characteristics, suitable for different regulation requirements.
The valve body adopts a carbon steel casting structure, with high outer strength and inner lining fluorine corrosion resistance, suitable for medium and low pressure strong corrosion working conditions.
The valve stem adopts an anti blowout structure, combined with fluoroplastic seals, effectively preventing medium leakage and improving operational safety.
Design specifications: comply with GB/T 4213 and HG/T 3704 standards.
Drive mode: Pneumatic (expandable to electric, hydraulic).
a. ZJHPF4 fully lined type: valve body fully lined/valve core fully lined
