SP 3000 Self-Operated Single -seat Pressure Regulating Valve Supplier

Convenient Combination

Normalized modular design allows the changeover betweendownstream and upstream pressure control mode, different regulation ranges and operatingtemperature can be performed with the replacement of extremely few parts.

Overload Safety

The safety shall be ensured under any circumstances. theself-operated regulator allows medium to enter the actuator, so the overload of the systemusually badly damaged the regulator. The overload protection mechanism of SP3000regulator can safely bear the overload pressure one or few dozens times higher than the upperlimt pressure of the regulation range. the overload pressure can reach the nominalpressure ofthe valve in most configurations.

Reliable Sealing

The valve stem ofSP3000 regulator is a long bellow structure , sealingO-ring is used as a back-up sealing method, which provides an extremely reliable sealing forvalve stem.

High Accuracy

The friction of bellow stem is far lower than conventional parking structurethe optimally designed spring and actuator will definitely find their best combination for procespressure, which makes the regulator have veryhigh overall control accuracy.

Easy Adjustment

The adjustment of pressure setting can be easity done by turning ofadjustment nut, the adjustmentoperation is more easy and fast due to the elimination ofconventional pillars structure.

Strong Adaptability

There are multiple actuator types,valve plug structures, rubberparts materials can choose to meet the operational requirements of different mediumand temperatures.

Low Leakage

Single-seat plug has very low leakage during the closing of the regulatorthe soft-sealed plug can completely shut off the flow and make the system enter into aholding-pressure status.

Stainless Actuator

As an important part of the reguator, the actuator is made of stainless plate to ensure its high pressure-strength and long service life.

Easy Maintenance

The selection criteria of the every structure of the SP3000 regulator is tomake sure the most convenient installation and maintenance while ensuring the performancerequirements are met.

The top-mounted push-down installation method allows you to inspect and maintainthe internal parts without any special tools before disassembling the regulator.

The bonnet central alignment method is adopted to avoid all unnecessary repeat matchingoperation , the internal part has sufficient clearance to make sure itself can be easity taken out orput in, the dissembling of the internal parts can be easily performed even the carbon steel requlatorrusts after long-term operation.

Universal Parts

SP3000 requlator has estremely high parts universality with the wholeself-operated products series manufactured by our company, it helps to reduce theinventory of spare parts.
