The Robertshaw R77-24 Invensys R7724 Temperature Control Valve is a versatile and reliable solution for regulating temperature in various applications. This valve is designed with a pneumatic actuation system, which allows for precise temperature control through compressed air.
The R77-24 valve body is made of brass, providing durability and resistance to corrosion. It features a 1/2 inch NPT inlet and outlet connection, making it suitable for use with standard piping systems. The valve comes with a stainless steel diaphragm and an armored stem, ensuring long-lasting performance even in harsh environments.
The valve's temperature control is achieved through a thermocouple sensor, which accurately measures the temperature of the process fluid. The sensor sends a signal to the valve's solenoid valve, which in turn adjusts the position of the diaphragm to control the flow of fluid. This results in consistent temperature regulation, maintaining the desired temperature within 2 F ( 1 C) of the setpoint.
The R77-24 valve is also equipped with a pneumatic positioner, which further enhances its temperature control capabilities. The positioner adjusts the air pressure to the valve's actuator, ensuring that the valve reaches the desired position for optimal temperature control.
Additionally, this temperature control valve comes with a fail-safe position, which returns the valve to a specific position in case of power failure or other issues. This feature helps prevent damage to the system and ensures continued operation when power is restored.
The Robertshaw R77-24 Invensys R7724 Temperature Control Valve is suitable for use in various industries, including food and beverage, pharmaceuticals, and chemical processing. Its compact design and easy installation make it a popular choice for applications where precise temperature control is essential.
This valve can handle a maximum working pressure of 150 psi (10 bar) and a temperature range of -40 F to 350 F (-40 C to 177 C). It is CE and RoHS compliant, ensuring that it meets the highest standards for safety and environmental regulations. With its robust design, precise temperature control, and versatile applications, the Robertshaw R77-24 Invensys R7724 Temperature Control Valve is an excellent investment for any temperature control system.
