is there a standard pattern for 3 way valves in other words would the solenoid\electrical bit from this
http://www.toolstation.com/search.html?searchstr=60151
fit on the pipework bit of a potterton msv322 3 way valve
or this one http://www.screwfix.com/app/sfd/sea/searchresults.jsp?_dyncharset=UTF-8& amp;q=&n=53314&pn=1&pd=1&pi=1&cn=1&cd=1&x=0&y=0
if not are the ports a simmilar spacing appart[will the tool station valve fit in with minimum tweaking of the pipework ] cheers
or would a replacement potterton electrical bit be cheaper or easier
