DLT Constant Flow Valve (Flow 103L/min, Pressure 40bar)

DLT Stainless Steel Flow Control Valve (1/2″~1″)

Features: DLT is a self-operated flow control valve. Utilizing the line pressure differential of the medium, it maintains a stable output flow largely unaffected by system pressure fluctuations. DLT also allows for flow adjustment and features a calibrated scale for flow indication and a locking mechanism to secure the selected opening.

Uses: Constant flow valves are widely used in automation, cooling systems, experimental apparatus, and control systems

Commodity name: DLT Constant Flow Valve (Flow 103L/min, Pressure 40bar)
Commodity ID: EG00840
小标题: DLT Stainless Steel Flow Control Valve (1/2″~1″)

○ Constant Flow Range: 1～150L/min ○ 40bar, -45℃～+180℃ ○ Regulates flow rate and maintains a constant output flow, mainly unaffected by system pressure fluctuations

Application of Sealing Materials

Material Code	Materials	Uses
N	NBR (Standard )	For non-corrosive media like water and oils; -35℃～+90℃
F	FPM (optional)	Resistance to acids and bases; suitable for most media; intolerant to ammonia;-25℃～+180℃25°C to +180°C.
E	EPDM (optional)	For ammonia, alcohols, ketones, and aldehydeS; incompatible with mineral oil; -45℃～+130℃.
