SP 592 Self-Operated Pressure Regulating Valve Factory

Excellent Micro Pressure Control Performance

The pressure requlating valve takes manymeasures to adapt to precise and stable micro-pressure control,

Amplify Lever force

The pilot operation mechanism is amplify the pull force of the lever. Themicro-pressure control should generate micro push on the diaphragm, The pure expanded diaphragmarea will lead to too huge valve volume, The lever can amplify the push to 6 time for control withoutthe need of increasing the walve wolume.

Nozzle Pilot Valve

The control performance of the pilot-valve determines the control capabilityof the whole pressure regulating valve system, For the micro-pressure control, any friction andresistance will severely affect the control effect. The pilot-valve plug is designed as the nozzleretaining plate structure without any sliding friction,so it is very high in control sensitvity,

Back-Pressure Control

For the pneumatic system, the back-pressure control is the most stableThe gas be input to the bilateral diaphragm case of the main-valve. The back diaphragm case canadiust the released gas fiow via the pilot valve nozzle for stable and precise control.

Embedded Pressure Reducing Valve

The power gas of the pressure regulating valve of the pilotvalveis from the gas aheadof the upstream,Generally the up stream pressure is higher and changes, Theembedded pressure reducing valve in side the pilot valve can reduce to the low and stable pressure fromthe higher pressure of the upstream and ittothecontrol system ofthe pressure regulating valve.

Filter

It is the precise pneumatic instrument of the pilot valve and requires clean control gas. Thepilot pressure tube of the pressure requlating valve includes includes a filter to quarantee clean gasto the pilot valve.

Low Start Pressure

The main valve is drive by lever, so the pressure regulating valve can normallystart and adjust the pressure requlating valve by using 15KPa upstream pressure.

Withstand Pressure Difference

The balance main vake plug can make the pressureregulating valve with stand higher pressure difference.

Soft Sealing Seal

The valve plug is designed as softwore sealing structure and caneasily cut off the flow.No Packing---Any friction resistance will affect the control precision of the pressure regulatingvalve at the micro -pressure control. Sp592 pressure regulating valve without packing makes the regulatingmechanism have highly sensitive and reduces leakage point.

High Precision

The high-sensitivity pilot valve provides a high control precision of thepressure regulating valve.

Low Over Control

The less over control is expected for any control system, $P592 pressureregulating valve is a once regulate the flow and the reduction ratio is extremely, so it easil generateover control. The nozzle of the pilot valve is a rewind valve plug. When the pressure is over, the nozzlevalve plug will quickly open two diaphragm case make the pressure to balance and quickly reducethe fow to minimze over control,

Overload Safety

To reduce the infuence of the parts gravity for control pressure. The wholeregulating device of the pressure regulating valve should be designed as light and precise as far as possible.The downstream pressure is very low during normal operation, The force on the regulating device is verysmall, The overioad is unavoidable in actual operation, The downstream pressure can reach the upstreampressure at abnormal state.At this time, the push force generated by the diaphragm assembly is verydestructive to the regulation device.The overload device of the pressure regulating valve can effectivelyuninstall the overload force and avoid damage to the regulation device. Namely when the pressure regulating valve is operating. in most case, the diaghragm case of the actuator can fully withstand themaximum operation pressure of upstream and it will not be damaged.

Easy Pressure Regulation

The screw regulation device can realize easy, corvenient and quickpressure regulation.

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 SP592 regulatoris to make sure the most convenient installation and maintenance while ensuring theperformance 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 repeatmatching operation, The internal part has sufficient clearance to make sure itself can be easitytaken out or put in.

Universal Parts

SP 592 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.
