Product Description
Download Instruction Manual Please Visit Our Website:


SP21M Pressure Regulator is a Internal-setting Pilot Control direct-operated pressure regulator. It can be use for downstream pressure control. The lowest control pressure is 20 KPa and the highest control pressure is 900 KPa. The lowest operating temperature is -48ºC and the highest operating temperature is 120ºC.



Compact Structure---The embedded sping structure makes the pressure regulating valve more compact and well protected.

Easy Pressure Regulation---The screw regulation device can realize easy, convenient and quick pressure regulation.

High Precision---SP21M pressure regulating valve applicalbe to the high pressure control, fixed net difference spring action to produce the equivalent of the control pressure is very small. The pressure regulating valve has high control precision.

Withstand Pressure Difference---The balance main valve plug can make the pressure regulating valve withstand higher pressure difference.

Soft Sealing Seal---The valve plug is designed as softwore sealing structure and can easily cut off the flow.

Stability Control---The setting regulator and main control valve are mutually independent control, do not interfere with each other, to make the control more stable.

Overload Safety---The safety shall be ensured under any circumstances. The pressure regulator allows medium to enter the actuator, so the overload of the system usually badly damaged the regulator. The overload design mechanism of SP21M regulator can safely bear the overload pressure one or few dozens times higher than the upper limit pressure of the regulation range. The overload pressure can reach the nominal pressure of the valve in most configurations.

With Pressure Gauge---The pressure gauge is standard configuration of the pressure regulating valve. It make the installation and commissioning more convenient.

Easy Maintenance---The selection criteria of the every structure of the SP21M regulator is to make sure the most convenient installation and maintenance while ensuring the performance requirements are met.
    The top-mounted push-down installation method allows you to inspect and maintain the internal parts without any special tools before disassembling the regulator.
    The bonnet central alignment method is adopted to avoid all unnecessary repeat matching operation. The internal parts has sufficient clearance to make sure itself can be easily taken out or put in.
    Universal Parts---SP21M regulator has extremely high parts universality with the whole self-operated products series manufactured by our company. It helps to reduce the inventory of spare parts.

Remark: The theoretical precision indicates the theoretical pressure deviation of the valve under 10-50% travel and constant pressure difference. It will be affected by the pressure difference change and flow in actual application. The actual theoretical precision is completely by the process parameter.
