Send RequirementPrecise Flow Control, Built for Repeatable Performance
Velqor flow control and needle valves are precision-machined for accurate metering and throttling across hydraulic circuits. They're available as pure needle-type flow control valves or with an integrated check (non-return) function, in inline, panel-mount, manifold-block, and cartridge configurations — built around your circuit design and approved drawing.
- Fine adjustment knob for repeatable flow metering
- Available with or without an integrated check (non-return) function
- Inline, panel-mount, and manifold-block mounted configurations
- Cartridge-style option for compact manifold integration
- Material and seal options based on requirement

Frequently Asked Questions
What's the difference between the DRV and DV series?
The DRV series combines needle-type flow control with an integrated check (non-return) function, while the DV series is a pure flow control valve without a check valve. The right choice depends on your circuit design — share your requirement and we'll help confirm it.
Can these valves be manifold mounted?
Yes. DRV-MB, DV-MB, and DVP series are manifold-block mounted, and the DVE is a cartridge-style valve built for direct manifold bore integration.
What flow and pressure ranges do these valves cover?
Typical ratings run up to 350 bar and 300 l/min depending on valve size and seal selection. Final ratings are confirmed against your approved drawing or specification.
Are these valves suitable for meter-in or meter-out circuits?
Yes, needle-type flow control valves are commonly used for both meter-in and meter-out speed control. Share your circuit design so we can help confirm the right configuration.
What port sizes are available?
Typical port sizes range from 1/8" to 1-1/2" NPTF (DN6 to DN25), confirmed per requirement.
Can Velqor manufacture as per drawing or sample?
Yes. We regularly manufacture to an approved drawing, sample, or specification provided by the buyer.
What materials and seals are available?
Common configurations use carbon steel, stainless steel 304, or stainless steel 316 bodies with NBR, FKM, EPDM, or MVQ seals, confirmed per requirement.
Can Velqor support bulk export orders?
Yes, Velqor is set up for export-ready packaging and documentation. Share your destination country and quantity so we can confirm logistics and lead time.
