DP27 Spirax-Sarco Pressure Reducing Valve Product Overview:
The DP27 Spirax-Sarco Pressure Reducing Valve is a pilot diaphragm regulator made of ductile iron and cast steel, with the main valve disc, pilot valve spool, seat, internal spring and strainer made of stainless steel. Any load changes or pressure fluctuations downstream will be fed back to the bottom of the pilot valve diaphragm, so as to adjust the opening of the main valve and ensure the accuracy and stability of the downstream pressure. The valve pressure adjustment ratio can reach 10:1, the control is accurate, when the pressure range exceeds 10:1, two pressure reducing valves can be used in series. This product can combine multiple pilot valves on the same main valve body to achieve two-stage pressure control, temperature and pressure control, remote control and other functions. Suitable for steam and compressed air systems. DP27 Spirax-Sarco Pressure Reducing ValveHow it worksThe DP27 Spirax-Sarco Regulator is normally activated in the normal position where the main valve is closed and the pilot valve is opened by spring force. Steam enters the diaphragm chamber of the main valve through the pressure control pipe through the pilot valve, and part of the steam flows downstream through the control hole. The control pressure applied to the diaphragm of the main valve increases, and the main valve is opened. As the steam flows through the main valve, the downstream pressure rises, and the downstream pressure sensing pipe feedback acts on the lower part of the pilot valve diaphragm (in order to ensure the stability of the downstream pressure, the downstream pressure sensing pipe should be installed), the force makes the pilot valve gradually throttle and close, and balances with the spring force on the upper part of the diaphragm, so as to maintain the pressure in the diaphragm chamber of the main valve, control the opening of the main valve, transport an appropriate amount of steam, and maintain a stable pressure downstream. When the downstream pressure rises, the feedback pressure increases, the pilot valve closes, and the pressure in the main diaphragm chamber is released from the control hole, so that the main valve closes tightly.

DP27 Spirax-Sarco Pressure Reducing ValveOrdering parameters and precautions:
Dear clients! If you would like to order our DP27 Spirax-Sarco Steam Pressure Reducing Valve, please specify the parameters when enquiring. The DP27G pressure reducing valve with the same series as this product adopts a soft seat, which can be used for compressed air and other industrial gases, but not for oxygen; DP27G is a soft-seated version for use in compressed air systems, or other industrial gases (not for oxygen); DP27T pressure reducing temperature control valve can accurately control the required temperature within the set pressure range; The DP27E pressure reducing valve with solenoid valve control has all the features of the DP27 pressure reducing valve, while its opening and closing can be controlled remotely by the solenoid valve.
