Commodity name: NK Throttle Valve (40bar)
Commodity ID: EG00820
小标题: NK Stainless Steel Throttle Valve (1/2″～11/4″)

○ Flow Range: 2～460L/min ○ 40bar, -45℃～+180℃ ○ Regulates flow rate precisely, provides visual reference, with a locking mechanism to maintain selected opening

Operating Instructions

To adjust valve opening, rotate the cylindrical handle. The top-mounted indicator rod moves vertically with the throttle position, featuring graduated markings that show the number of stem rotations. The integrated locking screw allows the selected opening to be securely maintained.
