調壓閥特性

Po=Fs/A – (Pi-Po) x a/A
Typical values
Orifice 0.062 diameter
Diaphragm effective diameter .92
Supply pressure effect [.062/.9]2≒1/200
→ 入口壓力每降100psi 出口壓力會上昇0.5 psi

Orifice 0.342 diameter
Diaphragm effective diameter 2.20
Supply pressure effect [.32/2.20]2≒ 3/100
→ 入口壓力每降100psi 出口壓力會上昇3 psi
