DVG High-Pressure Throttle Valve (Max. 350bar)

DVG/DVG-R Throttle Valve/Check Throttle Valve (1/4″~1″)

Uses & Features

DVG Throttle Valve: It can be used for the fine adjustment of liquid and gas flows and realize flow control and shutoff; there is a scale and the opening can be locked. Bulkhead nuts may be added as required to realize panel installation.

DVG-R Throttle Check Valve: DVG-R incorporates a check valve, combing both throttle and check functions. In the forward direction, it provides flow control and shut off functions by adjusting valve opening. In the reverse direction, as the valve is fully opened, it has no throttling function.

Technical Data  
● Working temperature: -35℃~+100℃ for carbon steel valves with NBR, -25℃~+180℃ for stainless steel valves with FPM stainless steel valves equipped with fluoroelastomer—25°C to +180°C. 
● Max.working pressure: see "Table of Technical Data
● Check valve cracking pressure: 0.5bar
● Body material: carbon steel or 304 stainless steel
● Core material: 304 stainless steel

    <span style="color:#028a84"> ○ </span> Flow Range: 1~480L/min <span style="color:#028a84"> ○ </span> 350bar, -35℃~+180℃ <span style="color:#028a84"> ○ </span> Regulates flow rate precisely, provides visual reference, with a locking mechanism to maintain selected opening. DVG-R also incorporates a check valve.

    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.
