I have a 25mm (1") pinch valve on a lime slurry (milk of lime) pnematically actuated with a full-on, full-off operation.

I am trying to locate a manufacturer(s) of excess flow falves for hazardous liquid service. The valves we currently are using are 3" 300#RF flanged valves manufactured by Guardian.

Rising stem ball valves for some applications. These are hard to come by and only manufactured by a very, very limited number of companies.

We have a 3 piece ball valve 48" Class 300. Noticed that when bolted together the straddle of the centerline is about 1/2degree off.

18” Metaltite ball valve (full-bore, fail-close), from KTM, cannot be operated (cannot command to open), even though the equalize valve was already opened and the differential pressure across the val

"Fire Safe" ball valve, particularly in accordance with API 607. My understanding is that the construction of the valve seat has both a resilient component for better sealing,

Glycerine & fatty acids @ 180'C and requires to seal at full vacuum.The valve currently installed has a glass filled seat which is being damaged after 3 months service and will therefore start to pass
