What is a logic valve?
Logic valves serve as a multifunctional valve for controlling the direction, flow and pressure by controlling the pressure signals in a hydraulic system, at the same time providing protection to the hydraulic pump.
How does a relief valve work?
Generally there's a spring holding the valve close, when the internal pressure is great enough, the valve opens - until the pressure drops. In some applications, there's a weight holding the valve closed.
What is difference between pressure reducing valve and pressure relief valve?
pressure relief valve relief the excess pressure which is developed in the syatem, while pressure reducing valve reduces the pressure and supply it to the system.
What is the purpose of the pressure regulation valve?
To regulate the pressure to a pre-determined amount.
What is different between pressure safety valve and temperature safety valve?
Pressure safety valve-are the valve who are designed such that it can control the pressure , like in the water blowers etc,and Temperature safety valve are those who are used to regulate the temperature like, in water boilers.
What is a logic valve?

How does a brake pressure control valve work?
the brake control valve is used to control the amount of hydrauic pressure form the hydraulic system to the brake system through the metering valve.
How does a relief valve work?
Generally there's a spring holding the valve close, when the internal pressure is great enough, the valve opens - until the pressure drops. In some applications, there's a weight holding the valve closed.
How do you test the tractor trailer protection valve?
Run the motor to air up the air system. Once this is done, cut off the motor. With the motor off, put the vehicle into gear. Then, you push in the tractor protection valve, which will release the spring brakes. You then pump the brake pedal (or the Johnson bar, if you prefer) repeatedly, and this will bleed out air pressure. When the air pressure gets low (below 60), the tractor protection valve should pop out automatically.
What is difference between pressure reducing valve and pressure relief valve?
pressure relief valve relief the excess pressure which is developed in the syatem, while pressure reducing valve reduces the pressure and supply it to the system.
When should you use a metal valve stem?
Metal valve stems are good for high pressure uses. However, they have "pull through" high pressure stems that work fine now.
Does the heater core have a pressure release valve?
no pressure release valve
How does Back-pressure valve work in dairy production?
Back pressure regulating valve is used in ammonia refrigeration plant to maintain the minimum pressure in the evaporator coils. It helps in preventing ice formation / choke upin the PHE chiller.
How do you check protection valve on tractor tralior?
With the vehicle aired up, push in the clutch, put the vehicle into gear, and turn off the ignition (leaving the tractor protection valve pushed in). When the motor is shut off, release the clutch. The motor will be off and the vehicle will be in gear, which will prevent you from rolling. Now, you simply pump on the brake pedal. This will reduce air pressure in the tanks (which won't build back up, as the motor is cut off). The tractor protection valve should pop out automatically when air pressure gets below 60.
What is high pressure valve?
A pressure valve is usually installed on water systems to prevent excess water pressure from destroying fixtures or other plumbing components. When the pressure exceeds the valve ratings the valve opens and releases water/pressure from the line.
Why does the pressure valve keep opening?
Too much pressure or defective valve.
What is the small valve in the center of the radiator pressure cap?
pressure-relief valve
