Product Description

Swing Check Valve is used to prevent back flow in the line. Flow is in a straight line through the valve resulting in minimal pressure drop. The disc swings into the open position as the media flows through the line. Back pressure in the line holds the disc in the closed position. Swing check valves may be installed in horizontal or vertical lines, but must be installed in proper relation to the media flow as indicated by the flow direction arrow marked on the body.

Resistance Strain Gauge is a kind of sensitive element by using resistance-strain effect to transform the strain of specimen into resistance change. It is the most widely used strain test element. The load cells used in weighing and measuring field mainly include resistance Strain Gauge type load cells, capacitance type load cells, vibrating string type load cells and so on, most of them are resistance strain gauge type load cells.

The resistance strain gauges produced by our company has the advantages of long liability and good uniformity, the functions of creep and temperature self compensation, suitable for batch production of alloy steel, aluminum ally and stainless steel load cells with high accuracy, and for producing other load cells and force and strain measuring elements.
