Welcome to inquiry, more favorable prices are waiting for you.


SP5000 relief valve is direct-operated upstream pressure regulating valve. It can use for sundry relief system. Especially apply to the low-pressure relief system of the tank and reaction kettle.
It can be applied to Nitrogen blanketing storage tank system.
The minimum control pressure is 0.5KPa 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).

Overload 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 regulator. The overload protection structure of SP5000 regulator can safely bear the overload pressure one or few dozens times higher than the upper limit pressure of the regulation range. 

High Precision Because No Packing---Any friction resistance will affect the control precision of the pressure regulating valve at the micro-pressure control. SP5000 Pressure regulating valve without packing makes the regulating mechanism have highly sensitive and reduces leakage point.
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.
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.
