You mean GLOBE valve and that would depend on the size of the valve and the maker

Difference between set pressure and blow-off pressure?
The set pressure is the pressure at which a relief valve starts to open. When the valve is open and relieving, the pressure will be higher or lower than the set pressure, depending on the system and the valve design. That is the blow-off pressure.
What is the purpose of geyser pressure valve?
The purpose of a pressure relief valve in a geyser is to release the pressure created inside due to evaporation of water.
What is the purpose of a pressure regulating valve?
it controls the pressure
What you mean by cold differential set pressure of a safety valve?
cold differential test pressure -The inlet static pressure at which a pressure relief valve is adjusted to open on the test stand. This test pressure includes corrections for service conditions of superimposed back pressure and/or temperature.
Why is to safety valve mounted on boiler drum?
the safety valve is mounted on the top of drum because, if the water level in boiler decreases a certain value, the temperature gets increased in water drum because of lack of water. So, increase in temperature result in high pressure in steam drum, as the safety valve is designed to withstand a certain pressure, after a cetain pressure, the safety valve is removed by high pressure of steam. this is why the safety valve is mounted on top of boiler drum. +++ Shall we sort out that lot? That answer is wrong. Its only link with water-level is that the valve has to be above the water anyway. If the boiler runs dry the safety-valve will not protect it. The safety-valve is there to prevent the steam pressure rising to a potentially a dangerous level. It is set to open at the boiler's designed working pressure.
Is the pressure drop through a globe valve less than through a gate valve?
HECK NO the globe pattern offers the most pressure drop because of friction losses
If a valve creates a back pressure of 1.5 to 2 bar on a pump what will be the pressure of liquid flowing through the tube on other side?
Valves, like other discontinuities, cause a drop in pressure as fluids flow through. The more fluid goes through the valve, the higher the fluid velocities within the valve will be, and the greater the pressure drop. If you are seeing 1.5 to 2 bar drop through the valve, the pressure at the outlet will be 1.5 - 2 bar lower than the pressure at the inlet. If you know the characteristics of the valve, you can figure the pressure drop at any given flow rate, but you need to know the pressure at either the inlet or the outlet to find the pressure at the other end.
How does a valve cause a pressure drop in terms of the individual molecules in the liquid?
Soo
What is the purpose of an externally equalized thermal expansion valve?
compensates for excessive evaporator pressure drop
How much drop should a gas valve when it comes on?
Most all manufacturers of gas valves have a pressure drop of one inch wg
If you have a bent valve will your oil pressure drop also is it drivable for about ten miles it's a VG30E V6?
I'm not sure the oil pressure would drop with a bent valve. I wouldn't drive it at all but if your driving to shop or home and don't want to pay to have it towed, drive real slow.
How do you define the coefficient of incipient cavitation?
The cavitaion index across a valve or pipe fitting is defined as the ratio of difference between upstream pressure and vapor pressure to the pressure drop across the valve or fitting. The index at which incipient cavitation, damage, or choked flow occurs is based on testing and depends on the type of valve or fitting.
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 porpose of a Leak detection pump pressure switch?
The purpose of a leak detection pump pressure switch is to immediately alter the system to pressure drop. These are most commonly associated with seal or valve failure.
Why is the pressure drop higher in globe valves than in gate valves?
The flowpath in gate valves is sraight. In a globe valve, the flow has to make at least one 90° angle (for some angle body valves) and usually more. Changing the direction of the flow causes pressure drop. Also, the minimum flow area of a gate valve is usually greater than the same size globe valve, making it more efficient. Energy in the flow is lost in expansions and contractions, and the loss of energy manifests itself as pressure drop. The fewer expansions, contractions, direction changes, and general disruptions of any kind in the flow, the lower the measureable pressure drop will be.
Where is the emergency shut-off reset button on a1994 Mazda B4000?
in my 2000 b3000 it is under the passenger glove box next to the fuel pressure release valve.
Does the heater core have a pressure release valve?
no pressure release valve
