CONTROL VALVE HAITAMA

HAITIMA H800 series control valves is a complete line of Heavy Top Guided globe style control valve, combine various
features with numerous of trim designs, these are suited to the most demanding process control requirements. All
valves are fully factory tested and meet the industry standards. The standard features is as follows:
 
Top Guided
Heavy top valve plug guiding provides the biggest support guarantee valve plug to be stable and rigid.
 
Single and Double Stage Lo-dB / Anti-caitation Trim
Replacing the conventional plug with the Lo-dB / Anti-cavitation design provides excellent noise attenuation or cavitation control.
 
Reduced Capacity and Low Flow Trim
A series of reduced area trim is available to provide wide flow range capabilities in all valve sizes. Optional trim to meet low flow requirements is also aailable.
 
High Pressure Capability
A variety of actuators are available to handle low to high pressure drop requirements.
 
Tight Shutoff
Class IV leakage is standard. Optional constructions meet IEC 534-60534-4 and ANSI/FCI 70.2 Class V and VI.
 
Hardened Trim
Provided as standard to handle high pressure drop application.
 
Trim Type
Standard construction offers either a quick change or threaded seat ring. This trim is unbalanced and uses no seals or pilots.
 
Environmental Packing
Low emission Garlock EVSP 9000 Packing is available to assure compliance with latest environmental regulations.
