The current valve being tested is a very simplified version of one of very first valves I scratch built when I first started messing with hpa. It can be seen here https://www.gatewaytoairguns.org/GTA/index.php/topic,172933.msg155948123.html#msg155948123I am including my sketch from that thread below along with a VERY generic sketch of its current form/function.

Primary advantage to balanced valve designs ...Easier cockingAble to use lighter hammers with LESS cyclic vibration during the shotPressure assisted closing type can be much more efficient due to short dwell if set up to be so and also Quieter muzzle reportBut do agree that there primary use is larger calibers or operating at the upper level of output in the caliber of use.

Keeping the masses that move down to a minimum. The powder burner world has an advantage where most all forces during the shot cycle are inline to the bore. Conventional pcp’s have their mechanism offset. Every little bit helps. Dave
What is the dimensions of the Vet’s valves chamber? Id and lengthDave
I was more curious about how much room there is to work with. By ‘chamber’, I should have said ‘valve housing’. I’m not familiar enough with the vet. Dave
What are you guys trying to do with the TAIPAN valve ?
Bigger stem diameter would be the easiest depending on how big it is versus the body stem guide. It sounds as though the vent is big enough. Dave
