MGA has just received a massive stock delivery of Check Valves from Val-Matic, our US manufacture of Check Valves. Due to our on-going success in the water industry supplying the major Water Utilities with a range of Check Valves from 3” to 24”, we have now increased our stock to carry Check Valves in 3”, 4”, 6”, 8”, 10”, 12”, 14”, 16”, 18”, 20” and 24”.
Not only is MGA now..
Valmatic produced a white paper to test the dynamic characteristics of their Check Valves in order to identify which Check Valves perform the best under conditions of extreme water slam. For a more detailed explanation of the methodology, the testing and the findings, please read the white paper on Check Valves. This is a brief summary of the findings and the implications of the results on the contaminated/waste..
The Valmatic SwingFlex Check Valve – why choose them?
During our experiences talking to Design Engineers in the Water Industry, one of the main questions we are asked is….”Why is the Valmatic swing check valve better than the traditional swing check valve? Then we proceed to tell them exactly why!
The table below summarises the main points, but for more information read the white..
MGA Controls Ltd, ValMatic’s exclusive UK and European distributor, specified the Valmatic SURGEBUSTER check valve as a solution to a common problem experienced by engineers and consultants in the water industry. As per below article, MGA Controls supplied Valamtic SURGEBUSTER Check Valves to overcome the problem of noisy water slamming at an offshore windfarm.
We now have some picture of the very..

Direct acting solenoid valves
Direct operated solenoid valves
Asco Numatics have launched their 256/356 range of Solenoid Valves
This addition to Asco’s range of Solenoid valves creates a competitive and functional range of 1/8” and 1/4”direct operated solenoid valves. The 256/356 series of solenoid valves complements Asco’s current offering of solenoid valves,..
Three-way direct acting solenoid valves work in almost the same way as a two-way direct acting solenoid valve. The fixed core has an exhaust orifice running through it. The plunger has an upper seal and lower seal allowing flow to or from either the body seat or exhaust seat depending on the configuration.
Applications using three way solenoid valves
As three way solenoid valves operate in the..
Two Way direct acting Solenoid Valves
Available in two forms: Normally closed solenoid valves and normally open solenoid valves. Direct acting solenoid valves do not use a diaphragm, their seal is part of the moving core.
Two Way Normally Closed Direct Acting Solenoid Valves
In two way normally closed direct acting solenoid valves a spring holds the core against the seal. When the..
Two Way Pilot Operated Solenoid Valves
Pilot operated solenoid valves have two chambers that are separated by a diaphragm. Sometimes the diaphragm is not connected to the core and is know as indirect acting.
How do Pilot Operated Solenoid Valves work?
The upper chamber is connected to upstream through a pilot hole in either the cover or diaphragm. The media exerts a pressure that acts on..
A solenoid valve is an electromechanical valve that can be used to control the flow of liquid or gas. The solenoid converts an electrical signal in to a mechanical movement. The signal is sent to a coil and the movement occurs inside the valve.
How do they work?
How M&M solenoid valves normally operate is shown in the diagrams. A coil is assembled on to the valve body on an armature tube..
