marco pneumatic dispensing valve

Pre­cise dis­pens­ing. Com­pact design. Easy inte­gra­tion.

Direct con­trol input
The new mtv/pv/20a pneu­mat­ic dis­pens­ing valve from mar­co requires only a com­pressed air con­nec­tion and a 24 V trig­ger sig­nal – no addi­tion­al con­trol unit, no HMI. The trig­ger sig­nal can be sup­plied direct­ly by an automa­tion sys­tem, a robot, or a dig­i­tal I/O mod­ule. This reduces instal­la­tion time and gets the sys­tem up and run­ning quick­ly.

High cycle fre­quen­cy
This valve is elec­tri­cal­ly con­trolled and requires min­i­mal instal­la­tion space. It was devel­oped for pre­cise dos­ing appli­ca­tions with a high cycle fre­quen­cy of up to 20 drops per sec­ond.

Fea­tures and ben­e­fits:

• Elec­tri­cal­ly actu­at­ed with 24 V trig­ger
  ► Direct con­trol input – no con­troller or HMI required; easy inte­gra­tion into PLC/SPS automa­tion sys­tems
• Requires only com­pressed air and 24 V
  ► Sim­ple con­nec­tion and oper­a­tion – reduces sys­tem com­plex­i­ty
• 1 mm stroke open­ing
  ► Enables dis­pens­ing of media con­tain­ing larg­er par­ti­cles
• Dis­pens­ing fre­quen­cy up to 20 Hz
  ► High­er process speed – up to 20 dis­pens­ing cycles per sec­ond
• Com­pact design
  ► Ide­al even for tight instal­la­tion spaces or mod­u­lar sys­tem lay­outs
• Mod­u­lar design
  ► Inter­change­able com­po­nents such as valve insert, flu­id body, and car­tridge – reduced main­te­nance effort and spare parts inven­to­ry
• Media-sep­a­rat­ed actu­a­tor
  ► No wear parts in the actu­a­tor – main­te­nance-free and durable
• Suit­able for vis­cous, abra­sive and paste-like media
  ► Wide appli­ca­tion range with­out spe­cial valve require­ments – from adhe­sives to greas­es. Enables both dot and line dis­pens­ing
• Com­pat­i­ble with mar­co sys­tem com­po­nents
  ► Full sys­tem inte­gra­tion – reuse exist­ing mar­co valve seats and oth­er parts
