By maintaining a constant pressure difference between the spray steam or air pressure and the oil pressure in the oil-fired boiler (burner), the combustion efficiency is optimally controlled. 【Features】 ○ Always maintains a constant pressure difference between the two fluids ○ The bellows is connected to an internal valve ○ When a difference occurs between the pressure difference and the set pressure, the bellows expands and contracts ○ Self-regulating control valve that moves the valve based on the differential pressure ○ Unique and innovative control valve *For more details, please refer to the PDF document or feel free to contact us.

This variable port valve is a rotary type control valve that adjusts the flow rate by rotating the valve shaft. Additionally, it has a structure that allows the sleeve, which is combined with the valve shaft, to be moved, easily changing the opening area of the port through which the fluid passes. The maximum flow rate is determined by the movement of the sleeve, and the optimal flow rate is adjusted by the rotation of the valve shaft. Generally, when performing fluid control, the performance of the control valve affects the controllability, leading to the following conventional issues: - The pressure before and after the control valve differs between actual operating conditions and design conditions. - The Cv value of the control valve is determined for each diameter, and it can only be selected in stages, making it difficult to choose the optimal Cv value. - The range of flow rates used may exceed the valve's rangeability. By using this variable port valve, these issues can be resolved. *For more details, please refer to the PDF materials or feel free to contact us.*

This is an actuator that receives instrumentation signals such as 4-20mA and converts them into mechanical movements, such as the rotation of an operating shaft or linear motion of the shaft, proportional to the signals received. Hydraulic oil generated by a hydraulic pump is ejected from the injection pipe (hydraulic injection pipe relay mechanism), and the force coil that receives the instrumentation signal vibrates the injection pipe, sending hydraulic oil into the cylinder, causing the cylinder rod to extend and retract. This also rotates or moves the connected operating shaft in a linear motion. The movement of the operating shaft is fed back to the injection pipe through a mechanical restoration mechanism. In place of the mechanical restoration mechanism, we also offer a high-density, responsive SOP series that forms a servo system with electrical feedback. 【Features】 - Operation is reliable and trouble-free due to the powerful force of hydraulic power. - Each unit is robustly constructed. - The use of hydraulic injection pipes makes it resistant to contamination from hydraulic oil and highly durable. - Installation is simple. - Electrical work involves only wiring for the motor's power supply and input signals. - Mechanical work requires only linking the operating end. *For more details, please refer to the PDF document or feel free to contact us.
