Welcome to inquiry, more surprise prices are waiting for you.
SP439 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 0.3KPa and the maximum control pressure is 15KPa.
The minimum operation temperature is -54.4ºF (-48ºC) and the maximum operation temperature is 248ºF (120ºC).
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 control pressure is very low of the micro-pressure control valve, so the actuator generates limited push force. The lever force-amplification regulation device of the pressure regulating valve can amplify the micro push force of the diaphragm assembly by 6 times, so this pressure regulating valve provides excellent regulating and difference pressure withstanding performance. When the downstream system flow reduce to "0", the valve plug will shut off the flow at the micro-pressure state and hold the system pressure.
High Precision Because 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.
