Self-reliance type nitrogen sealed valve product features
1. without additional energy, can work in place of no electricity, no gas, convenient and save energy, reduce the cost.
2. nitrogen sealing device for the nitrogen, nitrogen release pressure setting is convenient, may be done under the condition of continuous production.
3. the large effective area of diaphragm pressure detection, set a spring stiffness is small, nimble, installation work balance.
4. using the packing design, the stem by less friction force, quick response, high control precision.
5. for nitrogen device adopts the operating command, stress ratio of up to 100:1, the relief effect is good, high control precision.
6.in order to ensure the safety of storage tank, the respiration valve must be set up in roof.
7.the respiration valve public security role, to avoid the conventional nitrogen sealing device in the opening and closing frequent defects easily damaged.
