Stainless Steel Double Ferrule Globe Valve J91 Series
The J91 series stainless steel double ferrule globe valve is a high-performance shut-off device specifically engineered for industrial fluid control systems. Manufactured from forged austenitic stainless steel, the cold-die forged valve body features homogeneous microstructure with exceptional mechanical strength and corrosion resistance. The innovative double ferrule connection mechanism combines preload force with elastic deformation principles, achieving dual sealing between pipeline and valve body through coordinated action of inner and outer ferrules, effectively resolving leakage issues common in single ferrule designs.
The precision-ground needle-type conical plug cooperates with hardened seat ring to deliver micrometer-level flow regulation and leak-tight shut-off within 0-40MPa working pressure range. Suitable for water, steam, petroleum products and non-corrosive gases, the valve operates reliably across -29℃ to 200℃ temperature range, meeting demanding service conditions in petrochemical, power generation and laboratory instrumentation applications.
Forged Body Double Ferrule Needle Valve
This upgraded needle valve features optimized structure based on conventional globe valves. Integral forging process ensures smooth flow passage without dead zones, minimizing media retention and pressure drop. The trapezoidal thread stem mechanism with PTFE self-lubricating bearings reduces rotational torque by 35% while guaranteeing over 10,000 cycles operational life. Specifically designed for pneumatic pipeline systems, the compact actuator interface allows easy integration with pneumatic control units for remote automation. Electro-polished surface treatment achieves Ra0.8μm roughness, complying with hygienic standards for clean piping systems.
Pneumatic Pipeline Solutions
Our pneumatic system components provide reliable fluid control for automated industrial processes. The modular design enables flexible configuration with various actuators and positioners, supporting precise pressure regulation and quick response requirements. All wetted parts utilize corrosion-resistant materials to ensure long-term stability in humid or chemically active environments.
