PONAR Wadowice Directional Control Valves
Structural Diversity and Mounting Configurations
Depending on the specific requirements of the designed or serviced hydraulic system, the product range encompasses various design types:
- Subplate mounted valves – featuring port configurations fully compliant with the widely recognized international CETOP standards.
- Threaded (in-line) valves – designed for direct installation within hydraulic lines, offering high installation flexibility (can be mounted in any working position) with connecting threads such as M18x1.5, M22x1.5, G3/8, or G1/2.
- Sectional valves – allowing for the modular configuration of control systems.
- Cartridge valves – dedicated for compact installation inside hydraulic manifold blocks.
Advanced Control Methods and Functional Variations
To ensure seamless integration with automation systems and manual overrides, these directional control valves are available in multiple actuation and monitoring options:
- Direct and pilot-operated designs – including electrically controlled solutions (e.g., the popular WE, IWE, and WN series), electro-hydraulic, as well as mechanically (roller) and manually (lever or knob) actuated variants.
- Proportional systems – proportional control models, including versions equipped with integrated digital electronics (type USAP/USAEP) and spool position monitoring sensors.
- Specialized and safety executions – intrinsically safe valves meeting ATEX directives, dedicated for operation in potentially explosive atmospheres (e.g., in underground mining).
- Integration of auxiliary functions – selected components come factory-equipped with cross-over relief valves, relief-check valves, or pressure adjustment capabilities in the actuator ports (A and B), along with manual emergency override buttons.
All supplied products are engineered to operate across a wide range of maximum flow rates and working pressures ensuring full repeatability of parameters and high operational tightness of the system.
