Overview
The right support for every metering task
Injection valves are mounted at the point of injection to connect the metering line. They protect against backflow and generate a defined back pressure.
With the PP, PVC, PVDF and stainless steel version, the injection valve with ball check is spring-loaded with a Hastelloy C spring, priming pressure approx. 0.5 bar (with R1/4 connector, spring made of stainless steel no. 1.4571, priming pressure approx. 1 bar). They may be fitted in any position.
The TT version without a spring is suitable for vertical installation from below. Valve springs can be retrofitted.
Injection valve sizes DN 10 and 15 have union nuts and inserts / hose nozzles in the scope of delivery.
Important: Injection valves are not absolutely leak-tight shut-off devices!
Your benefits
- Used as a non-return valve – in closed pipe systems to prevent mixing and backflow into the metering line.
- Used as a back pressure generator – in systems with a free outlet, to generate a defined back pressure.
