Compact Structure
The embedded sping structure makes the pressure regulating valvemore compact and well protected.
No Packing
Any friction resistance will affect the control precision of the pressureregulating valve at the pressure control. SP6000 Pressure regulating valve without packing makesthe regulating mechanism have highly sensitive and reduces leakage point.
Convenient Combination
Normalized modular design allows the changeover betweendownstream and upstream pressure control mode, different requlation ranges andoperating temperature can be performed with the replacement of extremely few parts.
Overload 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 mechanism of SP6000 regulator can safely bear the overloadpressure 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.
Easy Pressure Regulation
The screw regulation device can realize easy,convenient and quick pressure regulation.
Strong Adaptability
There are multiple actuator types, valve plug structures, rubber partsmaterials can choose to meet the operational requirements of different medium and temperatures
Balanced Valve Plug
The valve plug with O-ring balance structure can be used tominimized the influuence of the pressure difference on the non-balance of the valve stemand guarantee the pressure withstanding performance and precision of the pressureregulating valve. The plug select in unbalanced structure when the Kvs value less 10,only control the pressure of upstream.
Low Leakage
The soft-sealed plug can completely shut off the flow and make the systementer into a holding-pressure state. hard seal can rach level iV leakage.0
Stainless Actuator
As an important part of the reguator, the actuator is made of stainlessplate to ensure its high pressure-strength and long service life.
Easy Maintenance
The selection criteria of the every structure of the SP6000 regulatoris to make sure the most convenient installation and maintenance while ensuring the performance requirements are met.T
he top-mounted push-down installation method allows you to inspect and maintain the internalparts without any special tools and without remove the valve body.
The bonnet central alignment method is adopted to avoid all unnecessary repeat matching operation. The interal part has sufficient clearance to make sure itself can be easity taken out or putin. The dissembling of the internal parts can be easily performed even the carbon steel regulator rusts after long-term operation.
Universal Parts
SP6000 regulator has estremely high parts universality with the wholeself-operated products series manufactured by our company. it helps to reduce the inventoryof spare parts.
