Flowventil – fixed flow 0,5 L/min

Features and Benefits:

• Consistent accuracy: Delivers 0.5 L/min (range series offers 0.2–6 L/min), ideal for calibrating single- and multi-gas detectors.
• High inlet pressure: Handles up to 70 bar as standard; high-pressure version up to 150 bar, so the entire cylinder contents can be used without flow drop-off.
• Plug-and-play design: Single-stage construction with integrated pressure gauge (on most models) — open the valve and the calibration runs.
• Chemical-resistant materials: Nickel-plated brass body with Viton seals and a PTFE seat ensures long service life with most standard gas mixes.

Specifications:

• Fixed flow: 0.5 L/min (factory set)
• Max. inlet pressure: 70 bar (standard) · 150 bar (HP model)
• Outlet pressure: approx. 4 bar (internal to regulator)
• Connection (inlet): 5/8″ UNF C-10 (other variants: CGA 600, 1/4″ NPT)
• Connection (outlet): 3/16″ (4.8 mm) hose barb
• Materials: Nickel-plated brass body, Viton seals, PTFE seat
• Weight: ~0.24 kg (model 715)

With a fixed 0.5 L/min flow you eliminate uncertainty about gas volume and save time: attach the hose to the detector, open the cylinder, and the valve does the rest. This reduces gas consumption because excess gas isn’t vented during calibration, and you get repeatable results every time. The valve requires no further adjustment, reducing the risk of field errors and shortening service stoppages.

The valve ensures each calibration is done right the first time — no flowmeter, no tweaking, no doubt. The constant 0.5 L/min flow matches the requirements of most portable and fixed gas detectors, allowing you to standardize procedures across sites. The high inlet pressure means cylinders are fully utilized, lowering the cost per calibration, while the robust nickel-plated brass design minimizes downtime during replacement or service. The result is fewer false alarms, higher uptime, and demonstrable calibration quality that meets both internal and external audit requirements.
