Detailed Product Description：	Impulse valve A49Y-Pw543.2V Nominal diameter: DN25 Major parts material: Name of Material Chrome molybdenum vanadium steel body Chrome molybdenum vanadium steel valve Chrome molybdenum vanadium steel valve cover Stem spring steel Oriented set of stainless steel A49Y-Pw543.2V performance parameters: Working pressure (MPa) temperature (℃) start jumping height (mm) 3.136 5402 Safety valve First, use: For power plant boiler or pressure vessel to prevent the pressure exceeds the allowable stress values. Second, the structural characteristics: 1. Vertical hammer is heavy cone valve stem through the leverage and force the hammer and the valve flap, so that the valves remain closed, adjust the position of the lever hammer can jump start to reach the required pressure. 2. Impulse safety valves and main valve components supporting the use of impulse safety device. When the medium pressure increases to the set pressure, the impulse valve opens, the media from the pulse valve of the exhaust pipe into the main valve of the piston chamber, through the media, force push the piston down the exhaust valve open container media. When the pressure is reduced to allow the value, the impulse valve closed, the main valve piston pressure is reduced, by medium pressure valve closed. Third, pay attention: 1. Valve must be installed vertically. 2. Impulse safety valves and main exhaust pipe between the safety valve of the inlet tube a longer distance, electrical contacts and the main valve between the inlet pipe must be located no less than 5 times the diameter of the main entrance of the safety valve to avoid the main safety valve, because of the exhaust of electrical contacts and the correctness of the work of the impulse valve. 3. Impulse valve piping installation must be clean before. 4. The main safety valve should be secured to the frame, and the architecture should be able to bear the main reaction force generated when the exhaust valve, the main valve of the exhaust pipe hanger should be specific to avoid the exhaust pipe of the mass (weight) and Other forces acting on the main safety valve and main valve on the connection between the exhaust pipe flange. The lowest point in the exhaust pipe to install drainage pipe to prevent the main valve exhaust water hammer. 5. Impulse solenoid valve installed together with a bracket, a lever and solenoid valve connected to a flexible, do not have to open Shibuya phenomenon. Impulse valve to be installed in the ease of maintenance and debugging, less dust, vibration-free air is dry, the ambient temperature is not higher than 70 ℃ place, the relative temperature does not exceed 80%. 6. Spring-loaded safety valve of the back seat impulse lever and the bar part of the head of the arc from the end of the impulse valve should be transferred to the actual travel +1 mm. (With the guard at the top of screw adjustment) Impulse valve
