Built to Specifically Handle Medium-Pressure Pumps

Its main job is to give you precise control over how much liquid is flowing, and to make sure the system is working at the right pressure - not too high and not too low. This heavy-duty bit of kit is the brains of your operation for spraying or fluid transfer, with a super-accurate working-pressure-regulating valve that lets you tweak the spray pattern and flow rate to your heart's content. And to help keep it all running smoothly, even in really bumpy environments, it comes with a special pressure gauge filled with glycerine. This makes it super easy to see what's going on with your system at a glance, so you can make adjustments in no time - even when you're in the middle of a tough job in the field.

Product Showcase

The GI 40 is designed to slot right in with diaphragm pumps, working together to keep everything running smoothly by providing a solid interface for pressure management. To keep things running smoothly, the GI 40 needs to be able to measure the pressure in the system - and its rugged build means it can handle the daily grind of field work without losing its grip on fluid output.

What You'll Get from the GI 40

• Super Precise Control: The built-in regulating valve lets you dial in the perfect pressure for your specific task, making it easy to get the flow and pressure just right.
• Clear as Day: The glycerine-filled gauge keeps the needle from wobbling about and protects the inside bits, so you get a clear, steady reading every time.
• Color-Coded for Easy Use: The easy-to-read dial is color-coded, so you can see at a glance whether you're in a safe operating range.
• Just Right for Medium Pressure: It's been tuned to handle the flow and pressure of medium-duty diaphragm pumps, and it'll play nice with all types.
• Flexible Design: The GI 40 is built so that it'll work with a wide range of control valves - including linear and rotary - so you can hook it up to whatever automation you need.

Control Valve Details

• Max Flow Rate: This thing can handle up to 21.1 GPM (80 L/min)
• Max Pressure: It can handle up to 580 PSI (40 Bar) of pressure
• Connects Up Nicely: 1/2” NPT inlet and 3/8” outlet make it easy to hook up to your existing pump setup
• Temperature Tolerance: Don't worry - it can handle temperatures of up to 140° F
• Works with Actuators: It'll work with both electric and pneumatic actuators for automated operation
• Don't Panic - It Fails Safely: If power or signal is lost, the internal spring kicks in to keep things safe

How Control Valves Work

Control valves are the last bit of kit in an automated process - and they play a huge role in ensuring the right amount of fluid flows through the system. At the heart of it all is the control valve actuator - this bit gets a signal from a controller like a PID controller, and uses that to move the valve in the right direction. This movement lets you control the flow rate, pressure, and other key process variables to achieve the desired result.

The actuator can get its signal from loads of different places - including pneumatic (compressed air), electrical, and hydraulic. Pneumatic actuators are super reliable and respond fast, which makes them a popular choice for places where safety is really important. You can configure the actuator to fail open or fail closed, so that if the power or signal fails, the valve will automatically open or close to keep the system safe.

Putting it All Together

The operation of a control valve is all about working together - the actuator, valve stem, and valve body all need to be in sync if you're going to get the right flow and pressure. The actuator moves the valve stem, which shifts the valve plug, ball, or disc inside the valve body - and that's what opens up the right amount of space for the fluid to flow through. If you don't get the valve position just right, you'll end up with inconsistent flow and a system that's a real pain to keep stable.

Getting it Up and Running

As for fitting the GI 40 to your system, it's a doddle - all it takes is a quick screw, and you'll be up and running with a leak-free connection to your existing pump setup. You get built-in position feedback and sensors to help keep things running smoothly and make it easier to keep an eye on the system - not to mention the heavy-duty housing and glycerine-protected gauge that'll stand up to all the rough stuff your system throws at it.
