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 the different between composite safety toe and Alloy Lite Safety Toe?
There is no functional difference between a composite safety toe and Alloy Lite Safety Toe. They are made of different materials but meet the same performance standard.
How do you set Thermal safety valve?
*A valve thatrelieves pressure due to thermal expansion of liquid* You will see PSV's pressure safety valves on vessels with gas in them. You will see TSV's (Thermal Safety Valves) on pipelines/vessels full of fluid. The fluid in a blocked in pipeline in the sun will expand and quickly increase the pressure in the pipeline. The Thermal safety valve relieves this pressure due to thermal expansion. Essentially TSV's and PSV's Are the same physical device just used for different reasons, and so named differently. To complicate the issue you can also get combined temperature and pressure relief valves. These have two mechanisms 1. Normal spring to hold valve closed until set pressure is reached and valve opens. 2. Wax/oil filled probe, that as it gets to set temperature expands and opens valve. I have not yet seen these valves in the process industry, but there is one on my water heater at home. http://www.rmc.com.au/files/spec_sheets/HT501_1.pdf
What is the range of a safety valve settings for a boiler operation at 1000 psi?
There is no range on a safety valve. It lifts and relieves at whatever it`s setpoint is. As for the setpoint, it would be just above the maximum working pressure/temperature of the water side of the boiler as stated on the National Board Tag of the vessel.
What is pop up test in safety valve?
it is the pressure test used to determine the operating pressure of the pressure relief valves (CDTP).
Is safety valve and pressure valve mean the same?
yes
Why do you use a perforated plate at the bottom of a pressure cooker?
for safety . after a certain temperature the holes will tear

What is a T and P valve for electric water heater?
A T and P valve (Temperature and Pressure valve) is a safety device used in electric water heaters. It is designed to release excess pressure and temperature from the tank to prevent the tank from rupturing or exploding. When the temperature or pressure reaches a certain level, the T and P valve opens to release the excess pressure and temperature, allowing the heater to operate safely.
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.
How do you reset the temperature and pressure valve for electric water heaters?
The T and P valve is the temperature and pressure valve that is used on hot water tanks as a safety device. The temperature rating is up to 210 degrees F and a water pressure up to 150 psig. (pound force per square inch gauge) before the safety valve trips to relieve water and lower the pressure inside the tank. When the safety valve trips it allows cooler water to enter the tank to cool off the hot water that tripped the valve in the first place. The valve is usually located on the outflow of the tank as the temperature probe has to be located within 6 inches from the top of the tank where the water temperature will be the hottest. The valve is self resetting as soon as the pressure is reduced or the temperature lowers to below the set point of the valve.
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.

What is Food temperature safety zone?
The Food and Drug Administration (FDA) in the United States has identified the temperature danger zone as between 410F (50C) and 1350F (570)
What is the difference between normal flowrate and Actual flow rate?
Normal flow is 100% of the flow you actually expect. Rated flow is the maximum safety factor times the normal flow. i.e. for a maximum safety factor of 1.2 Normal flow = 100 gpm Rated flow = 1.2*100 gpm = 120 gpm Safety factors are applied to ensure a piece of equipment has some flexibility of operating conditions in its application. The minimum flow is the minimum safety factor time the normal flow i.e. i.e. for a maximum safety factor of 0.5 Normal flow = 100 gpm Rated flow = 0.5*100 gpm = 50 gpm If sized properly a pump specified in this way could operate at any point between 50 and 120gpm with no problems.
