SP3000 Self-Operated Single-Base Pressure Regulating Valve

Product overview

      SP3000 Bellow-balance Self-operated Pressure Regulator is a spring-setting direct-operated universal pressure regulator. It can be widely used for low-corrosive gases and low-viscosity liquids. With corresponding settings, it can be use for up-stream and down-stream pressure control. The lowest control pressure is 3Kpa and the highest control pressure is 3000Kpa. The lowest operating temperature is -48 ¡æ and the highest operating temperature is 300¡æ.

Product feature


¡øConvenient configuration - normalized modular design allows the changeover between down-stream and up-stream pressure control mode, different regulation ranges and operating temperature can all be performed with the replacement of extremely few parts.
¡øOverload safety - The safety shall be ensured under any circumstances. The self-operated regulator allows working medium to enter the actuator, so the overload of the system usually badly damaged the regulator. The overload protection mechanism of SP3000 regulator can safely bear the overload pressure one to 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.
¡øReliable sealing- The valve stem of SP3000 regulator is a long bellow structure. Sealing O-ring is used as a back-up sealing method, which provides an extremely reliable sealing for valve stem.
¡øHigh accuracy- The friction of bellow stem is far lower than conventional stuffing structure. The optimally designed spring and actuator will definitely find their best combination for process pressure, which makes the regulator have very high overall control accuracy.
¡øEasy adjustment - the adjustment of pressure settings can be easily done by turning of adjustment nut. The adjustment operation is more easy and fast due to the elimination of conventional standing pole structure.
¡øStrong adaptability- there are multiple actuator types, valve spool structures, rubber parts materials available to meet the operational requirements of different medium and temperatures.
¡øLow leakage - single-seat spool has very low leakage during the closing of the regulator. The soft-sealed spool can completely shut off the flow and make the system enter into a constant-pressure status.
¡øStainless actuator - as an important part of the regulator, the actuator is made of stainless plate to ensure its high pressure-resistance and long service life.
¡øEasy maintenance- the selection criteria of the every structure of the SP3000 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 part has sufficient clearance to make sure itself can be easily taken out or put in. The dissembling of the internal parts can be easily performed even the carton steel regulator rusts after long-term operation.
¡øUniversal parts – SP3000 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.
