Ringo Valvulas S.L products

This valve is used in gas pipelines and the actuator is powered directly from the line gas pressure. Valves actuator may be provided with line break detection system which closes the valve in case that the gradient of pressure drop in the line is greater than a preset value.

Fully Welded ball valves are available for those cases when leakage throughout atmosphere must be absolutely avoided such as in gas transmission pipelines. Valve is built in three pieces fully welded constructions.

The Top-entry valve types have a major application when a frequent maintenance must be carried out and the valve can not be easily removed from the pipe. In this valve model, all the internals can be easily dismounted by loosening the bonnet of the valve and removing the ball, the seat-holders and the shaft. When mounting the valve again, the seat-holders have a system to regulate the compression of these to the ball.

For sizes up to 6”, this type of valve can be used giving the same possibility of maintenance as top entry ball valve but being a construction much more economical.

Ringo Válvulas NCBV non contact top entry ball valves series are designed and produced according to API 6D/ ISO 14313, API 6A, API 6DSS / ISO 14723, BS5351, ASME B16.34 and other international standards as well as customer specifications on request. These valves are built of a single piece body with a bolted bonnet. This design is a robust construction that provides a good performance, smooth operation, minimum pressure loss, high Cv values and also allows bonnet disassembly on site to perform inspection, maintenance or repair without removing the valve body from the pipeline.

For those applications when large temperature variations are expected or fast shutt-off is required, this is the most ideal design. The seats are parallel and the disc has no contact with the seats during the stroke of the valve. Only at the end of the stroke the disc mechanism ensures the contact between seats and disc.

This is the most commonly used design (standard T-Pattern), providing large pressure drop across the valve.
