The NAF-ProCap capping valve is a high-tech valve for wood chip filling on a batch digester, one of the most critical applications in a pulp mill. It’s crucial that this is done in a safe and time-saving way and to control the time of the cooking sequence.

With an opening time of 15 sec, it is significantly faster to operate than competitor options. The NAF-ProCap will ensure that more daily blows are achieved resulting in a significant production increase. The unique design of the NAF-ProCap is based on a segmented ball valve. This design prevents wood chips from getting stuck between the housing and the ball.

The patented, unique design uses the eccentric hubs to load the seat providing tight shutoff. For safe operation, it comes complete with a jammer device for locking the valve in open or closed (filling or cooking) position.
