If you are new to irrigation systems and are at all unsure then please do call or email for more information.  

  • 1/2" BSP Female Thread 
  • 0.5bar minimum pressure required to open the valve 
  • Maximum pressure 10 bar 
  • Electrical operation 24 vac 
  • Manual operation as well as automatic 
  • Unobstructed flow path 
  • Single moving part for efficient and reliable operation 
  • High flow capacity 
  • Chemical and cavitation resistant 
  • Fully opening 
  • Flow control 
  • simple on/off/auto switch 

The Bermad 200 series is the most used valve by both landscapers and DIY Installations.  From the 200 series the most common valve is the 1" BSPF as this is compatible with most manifolds and can easily be interchanged without the need for thread reduces.  In other words you are probably best looking at the Bermad 1" Solenoid valves rather than the 1/2" 

The 200 Series valves deliver superior performance by taking advantage of latest technology. Made from specially-engineered, corrosion-free plastic, these diaphragm-actuated valves maintain an extremely high flow rate with exceptionally low head loss.

They are equipped with a control handle for flow adjustment and a manually-operated solenoid override in the event of a power failure.

The body of the valve is made from reinforced nylon making them very strong all metal parts are made with stainless steel and the diaphragm is made from natural rubber

The self-cleaning control feature of the electric models ensures operation in all conditions

Dimensions of the valve Length 70mm height 100 mm width 50mm 

Which size valve should I choose 

Bermad valves vary in size from 3/4" and up to 2".  The higher the flow then the larger the valve.  For most domestic properties a 1" valve will be sufficient.  Below is a chart that will give you an idea of the pressure loss that you would expect to see when the valve is in operation 

Size BSP  2m³ 3m³ 4m³ 5m³ 6m³ 8m³ 10m³ 15m³ 20m³ 30m³ 40m³
3/4" BSP 0.05 bar loss 0.12 bar loss 0.23 bar loss 0.3 bar loss

0.44 bar loss

0.8 bar loss

1.2 bar loss         
1" BSP 0.04 bar loss 0.07 bar loss 0.15 bar loss 0.2 bar loss 0.33 bar loss 0.7 bar loss 1 bar loss        
11/2" BSP zero zero almost zero still almost zero Still zero 0.05bar loss 0.08 bar loss 0.18 bar loss 0.3 bar loss 0.7 bar loss  
2" BSP  zero zero almost zero still almost zero Still zero still zero ish 0.05 bar loss 0.1 bar loss 0.2 bar loss 0.41 bar loss 0.7 bar loss

From the chart above we can see that most situations will require a 1" BSP Bermad valve and only in the most high flow environments would you use a 11/2" or a 2" Solenoid valve 

Thread size 

If you are unsure about thread sizes then please do read the information below 

How to measure a thread size

All (or most) thread sizes used in water fittings in the home and garden are measured in BSP (British Standard Pipe Thread). BSP can sometimes be referred to as BSPF or the Whitworth Pipe Thread. Pipe thread can be parallel or tapered depending on the use that the fitting is going to be used for.

This standard is used in the UK and it ensures that items that are used in the gas, water and Hydraulics industry are compatible. For example when you connect your washing machine to the mains water the adapter will use a standard BSP ¾” thread. This standard is used in many parts of the World outside of the United States.

Each thread can be measured using the very simple table below and there is no need to look at the number of threads per inch

To summarise the simplest way to identify which thread you have is to measure the outside diameter (male thread) or the inside diameter for a female thread

BSP Thread 1/4" 3/8" 1/2" 3/4" 1" 11/4" 11/2" 2"
Male Thread O/D mm 13 17 21 26.5 33.6 42 48 60
Female Thread I/D mm 11.5 15 18.6 24 30 38.5 45 57
Threads per inch (Take no Notice Of This) 19 19 19 14 14 11 11 11
