An intelligent one piece shaft design runs completely through the valve disc to prevent mechanical separation and eliminate the risk of shaft breakage caused by sudden water hammer in high pressure systems

The extended valve body neck configuration provides ample physical clearance for thick thermal jackets, allowing for clean heat insulated installations without hindering the operation of the manual handle

A heavy duty cartridge seat assembly ensures uniform compression and low operation torque while allowing for straightforward field replacement when performing routine long term valve maintenance

The top mounting pad conforms fully to standard ISO 5211 dimensions, making it incredibly simple to remove the manual lever and transition the valve to electric or pneumatic actuation later if required

A robust ten position notch plate and locking manual aluminium handle allow operators to fine tune and lock down fluid flow levels across precise increments for throttling applications

Valve body and concentric disc cast from premium ductile iron GJS400 to provide superior tensile strength and structural integrity over standard cast iron alternatives

Heavy duty internal valve stem precision machined from stainless steel AISI420 to ensure exceptional torsional rigidity and reliable long term corrosion resistance

Resilient valve seat manufactured from high grade EPDM rubber to deliver a bubble tight drop close seal across hot or cold water utility networks

Internal shaft components supported by high quality PTFE bushings and protected by NBR O-rings to ensure smooth rotation and prevent external fluid leakage

External handle assembly and notch locking plate formed from lightweight structural aluminium with stainless steel AISI304 connection screws
