Needle valve VT

manualflow controlmetering

Product summary
MVT metering needle valves are manufactured with PTFE fluid-contacting components (body and O-ring) and a PEEK valve spindle. External, non-fluid-contacting parts are anodized aluminum. Valves are available in three overlapping flow ranges. The safety handle limits torque and enables fine metered adjustment. MVT valves are suitable for regulating corrosive gases and liquids in pressure or non-critical vacuum applications and provide bubble-tight shutoff.

Design features

• Fluid-contacting materials: PTFE only (body and O-ring)
• Valve spindle: PEEK
• Rigid metal shell and anodized aluminum handle
• Safety handle to prevent over-tightening and enable fine control
• Eight turns to full open (non-rising stem)
• Orifice: 0.125 in (3.175 mm)
• Flow capacity: up to 30 SLPM (air) or 1.8 LPM (water)
