Precise Volumetric Control
Delivers accurate metering doses from 0.001 cc to 3 cc with adjustable volume setting, ensuring consistent dispensing results for critical lubrication and sealing applications.
MHV Series Precision Metering Valves for Grease Dispensing
Product Code: MHV1 (221100) / MHV3 (221300)
High-pressure volumetric metering valves designed for accurate grease and lubricant dispensing in automated systems. Provide precise dosing with suck-back control and durable stainless-steel construction.
Air-Actuated Balanced Spool Design
Normally-closed, air-operated spool mechanism enables fast and repeatable on/off control under pressures up to 10 MPa (1,450 psi).
Suck-Back Function
Built-in suck-back action prevents dripping after dispense, maintaining clean application and reducing material waste.
High-Pressure Capability
Compatible with high-viscosity greases and lubricants in demanding production environments such as automated assembly lines.
Durable Stainless-Steel Construction
All wetted parts are made of stainless steel with NBR and PU seals for corrosion resistance and long-term reliability.
Easy Maintenance
Simple structure and dedicated seal kits (MHV1 – 221101 / MHV3 – 221301) enable quick servicing and reduced downtime.
- Ideal for industrial equipment lubrication, bearing grease application, and precision assembly lines in grease and lubricant dispensing processes.
- Suitable for precise dosing of lubricants, sealants, or bonding agents in automated assembly systems for automotive and electronics production.
- Works seamlessly in high-pressure pump-fed systems equipped with line pressure regulators or shut-off valves.
- Commonly applied in multi-point metering setups with auto-changeover feed systems for continuous and uninterrupted dispensing.
