Easy Pressure Regulation
The screw regulation device can realize easy,convenient and quick pressure regulation.
Ovey load Safety
The safety shall be ensured under any circumstances. The self-operatedregulator allows medium to enter the actuator, so the overload of the system usually badly damagedthe regulator.The overload protection structure of SP5000 regulator can safely bear the overloadpressure one or few dozens times higher than the upper limit pressure of the requlation range.
No Packing
Any friction resistance will affect the control precision of the relief valve at thelow-pressure control.SP5000 presure reyief valve without packing makes the reguladingmechanism have highly sensitive and reduces leakage point.
Soft Sealing
The valve plug designed as soft sealing structure and can easily shut offthe flow.
Stainless Actuator
As an important part of the reguator the actuator is made ofstainless plate to ensure its high pressure-strength and long service life.
Easy Maintenance
The selection criteria of the every structure of the SP5000 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 beeasity taken out or put in.
Universal Parts
SP 5000 regulator has estremely high parts universality with the wholeself-operated products series manufactured by our company,it helps to reduce the inventory of spare parts.
