Spirax Sarco 25P Steam Regulator

25P Spirax Sarco steam relief valve structural features and uses:

The DP17/DP17G pilot valve type diaphragm pressure relief valve has been greatly improved on the basis of ordinary pressure reducing valve. Diaphragm uses a new type of material, and greatly processed the working area, so the valve upstream pressure or downstream load subtle changes can be accurately and timely feedback to the main valve diaphragm to adjust the opening of the main valve to ensure the stability of the downstream pressure.

Another outstanding feature of this product is that the same valve body can be installed and exchanged with a plurality of pilot valves to achieve temperature control, upstream pressure control, remote switch control, and the like at the time of voltage regulation.

Steam pressure reducing valve performance indicators:

Gray area: Indicates that the product is disabled.

ADE: Thread or flange connection EN 1092 PN25, ANSI 300LB.

ABC: flanged to ANSI 150LB.

FF: DP17G has a maximum operating temperature of 120°C.

Note: The pressure adjustment range for this series is 0.2-1.7 barg.

Spirax Sarco 25P series pilot valve type diaphragm pressure reducing valve can effectively control the steam temperature and/or pressure through diversified combination of the same main valve and different types of different valves. The design and manufacture of the Spirax Sarco 25P series pressure relief valve in the United Kingdom is entirely based on the needs of users. Its diversified portfolio is comparable to any other pressure reducing valve in the industry. In order to realize the independence and economy of multi-objective control equipment, multiple controls can be combined on the same main valve. Whether it is temperature control, pressure regulation or both, it can achieve rapid response, precise control and safety. . At the same time, all parts of the 25P series pressure relief valve can be disassembled for inspection or maintenance without having to move the main valve body in the pipeline. The correct selection and installation and maintenance can ensure long-term trouble-free work.

Spirax Sarco steam relief valve works: When the pilot valve spring is in the free state, the main valve and the pilot valve are closed. The pilot valve is opened by a spring force. Steam enters the main diaphragm chamber through the pilot valve. Part of the steam flows out through the control hole. When the pilot valve flows in more steam than the control hole, the control pressure in the main diaphragm valve increases. Main valve. As the steam flows through the main valve, the downstream pressure increase is fed back through the induction tube and acts on the diaphragm of the pilot valve to balance the spring pressure on the upper part of the diaphragm, so that the pilot valve is closed and throttled, the pressure in the main diaphragm is maintained, and the main valve is controlled The opening delivers the right amount of steam. Adjusting the spring on the pilot valve diaphragm changes the downstream pressure.

Spirax Sarco steam pressure reducing valve main features:

Pilot springs: Three-colored springs provide accurate control of different pressures from 0.2-14 bar g.

Temperature adjustment dial: set the required temperature quickly and accurately.

Temperature sensor: In the temperature control element, there is a liquid that does not need to be compensated to sense the change of the instantaneous temperature and provide accurate control.

100% test: Each 25P series pressure relief valve is steam tested at the factory to ensure trouble-free operation.
