Pressure Check Valves - Code 103

Parker Conflow’s Code 103 range are pressure check valves for use in underground mining that is safe and without open-end, which potentially prevents damage to gauges when regular checking is required.

Code 103 range enables the monitoring of hydraulic pressure on the leg and ram on powered roof supports of coal faces with the ability to screw it directly into each roof support leg. Three different connection types are available to suit individual applications, for added flexibility.

The action of screwing the adaptor into the Code 103M pressure check valve, causes a probe to push the valve ball off its seat and allows system fluid to enter the pressure gauge to register a pressure reading.

The Conflow Code 103NS and NSA Pressure Check Valve swivel adaptors are used in conjunction with a pressure gauge to enable readings to be taken at the tapping point.

Unscrewing the adaptor allows the ball to reseat, thus isolating the system from the gauge again. A one-way valve, Code 103 ensures that fluid cannot run back, for added safety.

Code 103 has a 3/8" BSP fitting and operates to a maximum working pressure of 690 bar.
