6.3.1 Bolt configuration
The bolt configuration of the plate heat exchanger varies between different
models. The major force of the plate pack is held by the tightening bolts (TB).
To distribute the force evenly over the frame plate and pressure plate, locking
bolts (LB) are used as well. The locking bolts can be shorter and can have
smaller dimensions. In the opening and closing procedure, it is important to
identify the tightening bolts (TB) and the locking bolts (LB). See the illustration
