Convenient Combination
Normalized modular design allows the change over between downstream and upstream pressure control mode, different regulation ranges and operating temperature can be performed with the replacement of extremely few parts.
Overoad Safety
The safety shall be ensured under any circumstances. The self-operated regulator allows medium to enter the actuator: So the overload of the system usually badly damaged the regulatorThe overload protection mechanism of SP9000 regulator can safely bear the overload pressure one or fewdozens ti mes higher than the upper limit pressure ofthe regulatjon range. The overload pressure can reachthe nominal pressure ofthe valve in most configuradjons.
Reliable Sealing
The valve stem of SP 9000 regulator is a long bellow structure. Sealing O-ring is used as a back-up sealing method,which provides an extremeyy reliable sealing for valve stem.
High Accuracy
The friction of bellow stem is far lower than conventional parkjng structure. The optimally designed spring and actuator will definiteyy find their best combination for process pressure,which makes the regulator have very high overall control accuracy.
Easy Adjustment
The adjustment of pressure setting can be easity done by turning of adjusting nut.The adjustment is more easy and fast due to the elimination of conventional pillars structure.
Strong Adaptability
There are multiple actuator types, valve plug structures, rubber parts materials can choose to meet the operational requirements of different medium and temperatures.
Bellows-Balance Valve Plug
The valve plug use bellows-balance type, so it is low obstruction, resistance to corrode and resistance to high temperature. It can reduce the unbalance force by the differential pressure to a minimum level ensure the differenital pressure resistance performance and control accuracy.
Low Leakage
Single-seat plug has very low leakage during the closing of the regulator. The soft-sealed plug can completely shut off the flow and make the system enter into a holding-pressure state.
Stainless Actuator
As an important part of the reguator, the actuator is made of stainless plateto ensure its high pressure-strength and long service life.
Easy Maintenance
The selection criteria of the every structure of the SP 9000 requlator is to makesure 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 partswithout 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 easity taken out or put in. The dissembling of the internal parts can be easily performed even the carbon steel regulator rusts after long-term operation.
Universal Parts
SP9000 regulator has estremely high parts universality with the whole self-operated products series manufactured by our company. it helps to reduce the inventory of spare parts.
