SP592 has Excellent Micro-Pressure Control Performance.

APPLICATION
SP592 pressure regulating valve is a micro-pressure regulating valve for pilot type and extensively applied for the micro-pressure control of different gas and micro-pressure nitrogen blanketing.
SP592 can be used for extreme low pressure gas controlling at the downstream. It is a direct-operated universal pressure regulator by Spring-setting.

It can be applied to Nitrogen blanketing storage tank system, Gas analytic systems' sample unit, etc.
The minimum control pressure is 0.15KPa and the maximum control pressure is 12KPa.
The minimum operation temperature is -54.4ºF (-48ºC) and the maximum operation temperature is 248ºF (120ºC).

PRODUCT FEATURES
1/2


 
Faster Delivery Speed Than Peers---- Modular structure design, so that my company's products have faster delivery speed than peers, at the same time have better interchangeability of parts (Only between our products).

Amplify Push Force ---The pilot operation mechanism is amplify the pull force of the lever. The micro-pressure control should generate micro push on the diaphragm. The pure expanded diaphragm area will lead to too huge valve volume. The lever can amplify the push to 6 time for control without the need of increasing the valve volume.

Nozzle Pilot Valve---The control performance of the pilot-valve determines the control capability of the whole pressure regulating valve system. For the micro-pressure control, any friction and resistance will severely affect the control effect. The pilot-valve plug is designed as the nozzle retaining plate structure without any sliding friction, so it is very high in control sensitivity.

Back-Pressure Control---For the pneumatic system, the back-pressure control is the most stable. The gas be input to the bilateral diaphragm case of the main-valve. The back diaphragm case can adjust the released gas flow via the pilot valve nozzle for stable and precise control.

Embedded Pressure Reducing Valve---The power gas of the pressure regulating valve of the pilot valve is from the gas ahead of the upstream. Generally the upstream pressure is higher and changes. The embedded pressure reducing valve inside the pilot valve can reduce to the low and stable pressure from the higher pressure of the upstream and it to the control system of the pressure regulating valve.

Start up by Low Pressure---The main valve is drive by lever, so the pressure regulating valve can normally start and adjust the pressure regulating valve by using 15KPa upstream pressure. 

Withstand Pressure Difference---The balance main valve plug can make the pressure regulating valve withstand higher pressure difference.

High Precision---The high-sensitivity pilot valve provides a high control precision of the pressure regulating valve.

No Packing---Any friction resistance will affect the control precision of the pressure regulating valve at the micro-pressure control. SP439 Pressure regulating valve without packing makes the regulating mechanism have highly sensitive and reduces leakage point.

Compact Structure---The embedded sping structure makes the pressure regulating valve more compact and well protected.
 
Stainless Actuator---As an important part of the regulator, the actuator is made of stainless plate to ensure its high pressure-strength and long service life.
 
Better Reliability ---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 status.
 
Overload Safety Protection---The overload is unavoidable in actual operation. The downstream pressure can reach the upstream pressure at abnormal state. At the time, the push force generated by the diaphragm assembly is very destructive to the regulation device. The overload device of the pressure regulating valve can effectively uninstall the overload force and avoid damage to the regulation device.

Easy Pressure Regulation---The screw regulation device can easy adjustment, convenient and quick pressure regulation.

Because the data too more, so please contact us for it.

Remark: The theoretical precision indicates the theoretical pressure deviation of the valve under 10-50% travel and constant pressure difference. It will be affected by the pressure difference change and flow in actual application. The actual theoretical precision is completely by the process parameter.
