US SUN valve overview

SUN valve produced in the United States, the type of valve can be divided into: the valve, balance valve, pressure relief valve, sequence valve, check valve, diverter valve, directional valve, solenoid valve, logic valve, shuttle valve, circuit saving valve ,and many more. One of the most significant advantages of the SUN plug-in valve in the United States is its free-floating valve end, which allows its close-fitting working assembly to float within the valve body to reduce its sensitivity to mounting torque and to prevent its internal moving parts from becoming stuck may. Clean or inspect the plug-in valve without having to change the valve to set or remove any plumbing. SUN plug valve internal working components, are heat treatment, processing wear-resistant, impact-resistant, anti-fatigue, long service life. SUN In-line Valve Socket Unique Considerations To ensure valve reliability, the SUN In-line valve sockets consider: 1) The outside diameter of the threaded shoulder allows the valve to be inserted into the socket to ensure centering. 2) The free float accommodates the eccentricity between the end of the plug-in valve and the socket. 3) The SUN plug-in valve float design allows for higher mounting torques, allowing the valve to be tightened to avoid loosening or oil leakage. 4) Shoulder flat mouth from the stop action, to withstand the load caused by the thread, to avoid any load or lead to deformation of the plug-in valve to ensure that the alignment of the centerline. 5) Put the thread in the middle to get the maximum flow capacity of the valve to reduce the influence of eccentricity, and distribute the thread load to the deep layer of the oil circuit board. 6) The stop at the bottom of the jack supports the float of the valve, and the assembled wire is used only for the valve combination. 7) The uniformity of the SUN ports gives the design greater flexibility and reduces the need for cutting board tools. The role of the United States sun valve sun valve is adjusted to reduce the inlet pressure to a certain outlet pressure and rely on the energy of the media itself so that the outlet pressure automatically maintain a stable valve. From the hydrodynamic point of view, the valve is a local resistance can change the throttle element, that is, by changing the throttle area, the flow rate and fluid kinetic energy change, resulting in different pressure loss, so as to achieve the purpose of decompression. Then rely on the control and regulation of the system adjustment, the valve pressure fluctuations and spring balance, the valve pressure in a certain range of error remains constant. The role of the United States sun valve The role of pressure reducing valve is based on the valve flow channel to reduce the local resistance to water pressure, water pressure drop range by connecting the flap valve or piston on both sides of the import and export of water pressure automatically adjust . Constant pressure than the principle of decompression is the use of valve body floating piston hydraulic ratio control, import and export side decompression ratio and the import and export of piston area ratio is inversely proportional. This valve works smoothly without vibration; there is no spring in the valve body, so there is no spring rust, metal fatigue failure considerations; good sealing performance without leakage, so both under pressure (water flow) and then the static pressure 0 o'clock); Especially in the decompression does not affect the water flow. Water flow through the pressure relief valve, despite its large head loss, is generally energy-efficient due to reduced water wastage and reasonable system flow distribution and improved system layout and operating conditions. Media for steam occasions, should use the pilot-piston valve or pilot bellows-type valve. For the convenience of operation, adjustment and maintenance, the pressure relief valve should generally be installed on the horizontal pipe. sun valve installation 1. If the valve itself does not carry a pressure gauge, valve should be installed in the pipe above the valve before the pressure gauge. 2, if the medium contains impurities, may block the valve hole, the inlet valve in front of about 1 meter to install pipe filters, and filter the best number of mesh control in more than 20 mesh. 3. In order not to affect the use of decompression effect, taking into account the ease of installation and maintenance, pressure relief valve is generally installed in the horizontal pipe, bellows-type valve for the flip. 4. Pressure reducing valve before installation, look at the nameplate and certificate of compliance with the required valve type and other conditions consistent with the appearance of any serious damage. Rinse the pipe thoroughly, and rinse the pressure reducing valve. If the pressure valve of Shenzhen European Valve is stored for a long time, you need to fully clean the inside of the valve body of the pressure reducing valve. 5. In order to prevent accidental overpressure in the valve, a safety relief valve should be installed about 4 meters on the outlet of the pressure reducing valve, just in case. 6, before installation must pay attention to the direction of the arrow on the valve body, the arrow points to the direction of medium flow, can not be installed anti, otherwise the valve will fail, causing accidents. sun pressure reducing valve selection 1. Pressure relief valve is usually the valve after the pressure P2 should be less than 0.5 times the pressure before the valve, that is, P2 <0.5P1.2. Each pressure relief valve spring only in a certain outlet pressure range Within the applicable, beyond the scope of the spring should be replaced. 3. In the medium temperature is relatively high occasions, the general choice of pilot-piston valve or pilot bellows valve. 4 media for the air or water (liquid) occasions, the general should choose direct-acting membrane-type valve or pilot-type membrane valve. 5 media for the steam environment, should use the pilot-piston valve or pilot bellows-type valve. 6. For the convenience of operation, adjustment and maintenance, the pressure relief valve should generally be installed on the horizontal pipe. US sun valve how to adjust 1, close the valve in front of the valve, open the valve after the valve to create a lower pressure environment; 2, the adjustment screw counterclockwise rotation to the top position (relative to the minimum outlet pressure), and then Close the valve after the valve; 3, slowly open the valve before the valve to fully open; 4, clockwise slowly adjust the screw, the outlet pressure adjusted to the required pressure (subject to the gauge pressure after the valve) ; Adjusted, the lock nut lock, open the valve after the relief valve; 5, such as the outlet pressure is higher than the set pressure adjustment, the first step from the beginning to re-adjust that only from low to high pressure . SUN valve produced in the United States, the type of valve can be divided into: the valve, balance valve, pressure relief valve, sequence valve, check valve, diverter valve, directional valve, solenoid valve, logic valve, shuttle valve, circuit saving valve ,and many more.
