The role of stainless steel precision pressure reducing valve is mainly have the effect of regulation, is not suitable for cutting off.
Therefore, generally due to factors such as structure design, there is a leak amount is allowed.
But when the valve closed, and in severe leakage, is usually caused by stem length not comfortable, when the stem is too long, up and down movement distance is not enough, cause the valve core and valve gap, not normally closed;
Also the stem is too short, there is space between the valve core and valve seat, not fully contact, causing the closed lax internal leakage.
Solution: adjust the stainless steel valve gate valve stem, stem length, right is closed properly.
Stainless steel precision caused by the relief valve body oscillation because there are several kinds roughly: one, when the spring stiffness is insufficient, the output signal is not stable, easy to cause oscillation.
Second, the selected valve at the same frequency and system frequency.
Three, pipelines, base violent vibration, the valve vibration.
Fourth, the improper selection, valve working in small open degree there is a sharp change of flow resistance, flow velocity, pressure, when more than valve stiffness, poor stability, serious when produce oscillation.
