Remotely controlled valve

Abstract

A remotely controlled valve includes an electric motor and transmission for moving a valve stem or valve actuator. The operation of the motor may be controlled by a first input for power and analog signals. The valve is also provided with a programmable logic controller and a wireless module for receiving wireless control signals for controlling the operation of the motor which moves the valve stem or a valve actuator in a desired manner.

I claim: 
     
         1 . A remotely controlled valve comprising:
 a.) a housing including a central section, a top portion and a bottom portion,   b.) a motor and transmission positioned within the housing,   c.) a valve body connected to the housing and including an inlet and outlet, and a valve actuator connected to the transmission,   d.) a first power and analog signal input, and   e.) a programmable logic controller connected to the motor and controlling the operation of the motor.   
     
     
         2 . A remotely controlled valve as claimed in  claim 1  further including a wireless module connected to the programmable logic controller for receiving wireless data to control the movement of the valve actuator. 
     
     
         3 . A remotely controlled valve as claimed in  claim 1  further including a position sensor that senses the position of a shaft of the motor. 
     
     
         4 . A remotely controlled valve as claimed in  claim 2  wherein the top portion of the housing includes a plastic insert above the wireless module. 
     
     
         5 . A remotely controlled valve as claimed in  claim 1  wherein the programmable logic controller is preprogrammed with wireless protocols. 
     
     
         6 . A remotely controlled valve comprising:
 a) a housing including a central section, a top portion and a bottom portion,   b) a motor and transmission positioned within the housing,   c) a valve body connected to the housing and including an inlet and outlet, and valve actuator connected to the transmission,   d) a first power and analog signal input,   e) a programmable logic controller connected to the motor and controlling the operation of the motor and   f) a wireless input module connected to the programmable logic controller.
