[Knowledge] Straight travel regulator valve stem fine reason

Straight stroke valve stem thinner reason: it involves a simple mechanical principle: sliding friction, rolling friction small. Straight travel valve stem up and down movement, the packing a little bit tight, it will be very tight stem package, resulting in greater backlash. To this end, the valve stem is designed to be very small, packing and PTFE friction coefficient is often small PTFE packing, in order to reduce backlash, but the problem is sent stem thin, easy to bend, filler life is short. Solve this problem, the best way is to travel with the valve stem, which is the type of angular travel control valve, the valve stem than the straight travel valve stem thick 2 to 3 times, and the choice of long life graphite packing, stem stiffness Good, long filler life, but the friction torque on the contrary, small backlash.

Sheets Baler

Ecohydraulic baler is known for ability to process a variety of materials including factory clips, skeletons, sheet, steel cans, stampings, shapes, wire, tubing and white goods. The lid-type baler is ideally suited for baling voluminous or wear intensive scrap. The lid-style balers are most often utilized in scrap yards and industrial applications.

1) Adopt rotating cover-closing structure, large opening area of material box, especially suitable for large, empty and thin materials.

2) All moving parts are driven by hydraulic pressure and work steadily, double main pressure mode, tight and uniform beam block, high packing efficiency.
3) manual operation is simple, convenient, safe and reliable.
