One thing I could add is to check the direction of the OPEN arrow on top of the PIV. I once worked at a plant which had some PIV's that opened counterclockwise. [EMAIL PROTECTED] Ed Vining 4819 John Muir Rd Martinez CA 94553 925-228-8792

Post Indicator Valve (PIV) Spring Test (Annually) PIV's should be operated annually, through its full range and returned to its normal position. PIV's should be opened until spring or torsion is felt in the rod, indicating that the rod has not become detached from the valve. PIV's should be backed off one-quarter turn from the fully open position to prevent jamming. Kind Rgds. İyi çalışmalar.
