ZPL640F Lined Self-regulated Micro-Pressure Control Valve (referred to as pressure valve) operates without an external power supply, utilizing the energy of the medium itself as the power source for automatic regulation.
Product Overview
The product consists of an actuator and an aligned valve body. All wetted surfaces (including the valve interior and internal components) are lined with 3~5mm thick fluoropolymers via high-temperature molding, effectively isolating corrosive media from metallic components while enhancing the lining's service life and performance. The regulator features: Zero external energy required, Excellent sealing, Fast response, Precision control, etc. Main applications: Acid/alkali/salt solutions, Volatile gases, Permeative liquids, etc.
