Injection Valves
Chemical Dosing Pump
Injection Valves
Dosing pump injection valve with non-return valve serves a number of critical functions
ensuring the metering line remains free of chemical air-locks by generating a defined back pressure between
the dosing pump and injection point eliminating backflow into the metering line, protection against excess chemical
discharge or syphoning occurring particularly when mounted in zero pressure environments such as tanks and
vessels and ensuring the chemical metering line remains primed and intact.
Injection Valves PVDF
Injection valve manufactured in PVDF characterised by exceptional resistance to most aggressive chemicals
agents with hastelloy spring ceramic ball non-return valve and chemical resistant seals, tubing is connected
via the specially designed compression system suitable for high pressure applications providing an impermeable
chemical seal connection.
Technical Details
• Standard Seals Viton or EPDM ( Special
seals available on request )
• Compatible Tubing Material :- PVC - Polyethylene - PTFE - PVDF
• Tubing Sizes :- 4x6mm ( 18 l/hr Max) 8x10mm (110 l/hr Max )
• Supplied with dual
purpose male BSP installation threads
N.B. Compatible with most chemical dosing pumps

Solutions For All Metering & Measurement Processes
What is a Dosing Pump Injection Valve
An injection valve is the final "point of entry" in a chemical dosing loop it's primary function
is to generate a specific amount of backpressure to the dosing pump and to ensure chemicals are dispersed evenly into the flow
stream while preventing the process liquid from backing up into the dosing pump discharge line, integrating a high-quality injection
valve offers several technical and operational benefits often incorporating a spring loaded non-return valve that act as a specialized
check valve providing an artificial head pressure ensuring each stroke of the pump delivers a precise repeatable volume of chemical.
Elimination
of Siphoning
Processes that have the point of injection lower than the chemical storage tank gravity can cause chemicals to effectively "free-flow"
into the system even when the dosing pump is off to guard against this happening the injection valve
non-return mechanism plays a critical role by requiring a specific pressure to open effectively "locking" the line
against accidental siphoning.
Maintenance Simplicity
Most modern injection valves are designed for tool-free servicing requiring periodic cleaning
often being the most likely component to fail mainly due to chemical crystallization at the injection point into the
pipework they are designed to be easily removed and serviced without dismantling the entire discharge line.
