Válvulas de control hidráulico

Hydraulic control valves are used to start and stop fluid flow into cilindros hidráulicos o hydraulic motors. They can be operated either manually o electronically (accionado por solenoide). The number of cylinders or motors that a control valve can operate depends on the number of spools on the valve. The flow rates listed is the maximum allowed GPM (Gallons Per Minute) that can be put through a valve. A common example of a hydraulic control valve is the loader valve on a tractor.

Typically, there are seven hoses or steel tubes connected to the loader valve. If only six hoses or tubes; there is no Power Beyond Port on your loader valve. The 1st four are connected to your loader for the up, down, dump, and curl functions. The fifth line comes from your pump to feed your loader valve. The sixth line goes directly to your reservoir so that when the pressure relief valve opens the fluid is dumped directly to the reservoir. The seventh line is connected to the “Power Beyond Port” on your loader valve, which is used to power other valves beyond the loader valve. On some loader valves there is a “PB” stamped on the valve next to the power beyond port. Some loaders indicate their power beyond port with green tape or a green mark on the hose or valve. Some loader valves have a power beyond sleeve inserted in the power beyond port. This sleeve looks like a nut; however, it is 3 to 4 times longer than a normal sized nut. On some loader valves, there are no clues to help determine which connection is the power beyond port. Your owner’s manual may not even indicate the location.

A true third function kit allows you to independently control the flow of hydraulic fluid in and out of a cylinder (or a number of cylinders) with a monobloque o directional control valve, using a series of either separate switches or switches contained within a joystick. When the button is pressed, the solenoid opens the flow of fluid to the cylinder, either extending or retracting it. Our third function valve kit is powered by the power beyond port of your existing loader valve which will allow you to use multiple functions at the same time (i.e. curl bucket and close grapple).

Ventajas:

• Instalación sencilla
• Evita costosos añadidos de fabricación

Se utiliza comúnmente para añadir:

• Pinzas
• Sinfines
• Inclinación del quitanieves
• Soplador de nieve
• Escoba

El conector de conversión de potencia está diseñado para su uso en nuestros monobloques manuales y monobloques de solenoide para añadir otra válvula aguas abajo. Por ejemplo, si tuviera que conectar dos monobloques en línea, necesitaría el enchufe de conversión Power Beyond para conectar la primera válvula a la segunda (VER EJEMPLO A CONTINUACIÓN). Sin embargo, si simplemente va a conectar esta válvula a su válvula de carga, NO necesitará el conector de conversión.

Cada puerto está marcado.

Conexión "P": Puerto de presión o de entrada. Este puerto se conecta a su poder más allá de puerto en la válvula de su cargador, su poder más allá de la manguera, o directamente a su bomba.

Puerto "T": Puerto de retorno o del tanque. Este puerto se conecta a su tanque.

Puertos "A" y "B": Estos son sus puertos de trabajo que se conectan a sus cilindros o motor hidráulico

Puerto "N": Se utiliza para el tapón central cerrado o para acoplar varias válvulas en fila (se requiere alimentación más allá del tapón).

Yes, we offer forward, rear, dual, and float detents for our manually operated monoblock valves. Please contact us if you’d like to order them.

Below is a drawing of the DIN Connector wiring. The solenoid on the monoblock solenoid operated valves corresponds directly to this.

Nuestra válvulas de control can be used to replace any current hydraulic control valve or be used in conjunction with your current hydraulic control valves. Please view the diagrams below to see typical installation scenarios.
