Anti-siphon control valve |
摘要 |
An on/off valve, preferably of the ball type, with an anti-siphon feature. The valve has concentric opposite direction flow with open structured support elements to maintain the inlet tube properly positioned within the elongated housing. A cup-shaped poppet-type float valve prevents fluid from spraying out of air vents upon opening of the ball valve. The control valve is particularly adapted for indoor use.
