BTL regulating valves is compose of combination valves and flow control staff guage. Because equip with micrometer graduation and finger, when open rator turn hand wheel around, finger would move ten percent. BTL regulating valve equip with regulating disc to ensure flow, so it can accuracy control.

Seal facing of BTL regulating valves is stellite depesit, so seal faceing is more corrosion resistant, anti-abrasive and avrasion resistance.

BLT regulating valves is manual operate, liner fow regulating function, abrasion resistance.

If you want to equip with locking device, lease note you BTL requirement
