The special inner shape of the Maxomatic series ensures the following:
Moreover, optimal closing performance is achieved between the elastic membrane surface (elastomer with nylon reinforcement) and the machined metal seat.
The valve seat design provides a tight seal and minimizes wear on the seat in case of solid particles in the media.
The valves from the Maxomatic series has several benefits. See below:
The Maxomativ control valves play a critical role in various sectors ensuring precise flow and pressure management in a range of applications such as:
The various industries which the valves are suitable includes, but is not excluded to:
The MAXOMATIC system is composed of three key components:
By configuring one or more pilot valves, the system can address a variety of control challenges, all while utilizing a single main valve.
This flexibility makes MAXOMATIC an efficient solution for diverse control applications.
The Maxomatic valves are designed for flexible installation, allowing it to be mounted in any position to suit various system configurations.
Moreover, maintenance is straightforward and convenient, as the diaphragm can be replaced without the need to remove the valve from the process line, minimizing downtime and ensuring continuous operation.
Additionally, the valve features adjustable open and close speeds, enabling precise control to prevent potentially hazardous water hammer effects, which can cause damage to the system. This combination of easy installation, simple maintenance, and safety features makes the valve a reliable choice for various applications.
The applications of the control valves in the Maxomatic series are multiple. Below we have listed some of them:
The operation of the regulating device relies on three key components:
The diaphragm functions as both a shutter and, along with the spring, as an actuator. Its design allows it to move smoothly between fully closed and fully open positions without strain. The position of the diaphragm is determined by a balance of forces.
In the closing direction, these forces include the combined actions of the spring and the servofluid (the medium itself), with pressure levels adjusted by the pilot system.
In the opening direction, the medium's pressure acts on the lower surface of the diaphragm.
The conical spring provides a force that increases proportionally with the diaphragm's lift, enabling it to respond appropriately when the servofluid pressure changes, ensuring stable operation without chattering.
The pilot system senses the controlled parameter and adjusts the servofluid flow to modulate pressure on the diaphragm, moving it to achieve the valve lift necessary to maintain the desired control.
Once the valve reaches the position needed to meet the required capacity, the pilot resets, allowing the system to maintain a steady flow, thereby completing the control process.
