VBZ Ball VALVES
APPLICATION:
The VBZ series ball valve assemblies are used primarily to control the flow of a chilled or hot fluid in central air conditioning, heating systems, water treatment and industrial production. The valve’s actuator can be installed after valve body has been installed into system.
FEATURES:
• Two-way and three-way bodies available
• Female BSP and flanged end connections available
• Equal percentage flow characteristic
• Seat leakage of 0.01% of Kv, meets ANSI class IV
• 25 Bar (360 PSI) meets or exceeds pressure and temperature ratings of ANSI Class 250
• Stainless steel ball and stem are standard
• PTFE sealing for high close-off pressure
• Chilled and hot water 2° to 94° C (36° to 200° F), up to 50% glycol solution
