Spirax Sarco Spirax Sarco DP27 diaphragm valve Agents

Spirax Sarco valve agent in Shilong Valve Co., Ltd. [DP27 diaphragm valve Spirax Sarco Spirax Sarco DP27] [] diaphragm valve through the same main valve, different types of different valves diversified portfolio, can effectively control the steam temperature and / or pressure. [Spirax Sarco DP27] diaphragm valve design and manufacture entirely in accordance with the needs of users, and its diversified portfolio of industry without any other control valve can be compared. In order to achieve economic independence and multi-target control equipment, a variety of control can be combined on the same main valve, regardless of the temperature control, pressure regulator, or both together, can do rapid response, precise control, safe and reliable . [Spirax Sarco DP27 diaphragm valve] were able to break down all the parts inspection or maintenance without moving the line of the main body. The proper selection and installation and maintenance, to better ensure its long-term trouble-free operation. [Spirax Sarco DP27 diaphragm valve] to start leading a valve spring in a free state, the main valve and pilot valve is turned off. Pilot valve spring force to open, the steam into the main diaphragm chamber via the pilot valve, part of the steam is flowing through the control hole, when the pilot valve is greater than the inflow of steam from the steam out of the control hole, the main diaphragm valve control pressure, open the main valve. As the steam flows through the main valve, via incremental sensing downstream pressure feedback tube, in case the pilot valve diaphragm, the upper portion of the spring pressure balancing diaphragm, so that the formation of closed pilot valve is throttled to maintain the pressure in the main separator, the main control valve the opening of transport the right amount of steam. Adjustable spring pilot valve diaphragm can be changed on the downstream pressure.
