Triple-offset butterfly valves
HIGH QUALITY BUTTERFLY VALVES FOR HEAVY DUTY APPLICATIONS
- HIGH QUALITY with unique features
- CLOSER Gasket DOES NOT CLICK IN SEAT (cone-in-cone seating design)
- LONGER LIFETIME due to frictionless opening and closing
- SHORT DELIVERY TIME due to large stocks of components. (Sometimes within 1 week!)
Zwick Armaturen GmbH
Zwick is a leading German manufacturer with 40 years of experience in the production of triple-offset butterfly valves for heavy duty applications. Thanks to a modern well-equipped production and large stocks, they can often deliver very quickly.
Range
DN50 - DN2200 / 2" - 88"
PN10 - PN250 / ANSI 150# - 1500#
Designs: lug, double flange, butt weld and wafer
Unique valve seal
- 25° tilted cone
- Opens and closes frictionless
- Valve seal does not become deformed
Valve sealing options:
- Multi-layer metal/graphite laminations
- Multilayer metal laminations
Self-centering valve disc
The self-centering valve disc that is keyed to the shaft, preventing jamming of the valve in the seat due to thermal expansion.
Option: patented bearing seal
The reliable alternative to a ball valve, globe valve or gate valve.
- Compact design - standardized build length
- Easy and cost-effective to automate.
- Good control characteristic
- No dead space
- Spindle seal
- Metal to metal valve seal
- Fire safe - fire tested according to EN ISO 10497 / API 607 5th edition / BS 6755
- 2-sided sealing according to EN12266-1 Rate A /API 598 Zero Leakage /API 6D Zero Leakage
- Option: patented bearing seal to prevent penetration of medium into the bearings. (see sectional drawing)
Applications
Zwick TRI-CON valves are used in demanding industries on applications ranging from oxygen to flue gases, from cryogenic to superheated steam and in many chemical processes. TRI-CON valves have proven over the years to be reliable, safe and durable. Some examples of applications where TRI-CON valves are successfully used are:
Refineries - desulphurization systems and tail gas treaters / steam / ESD solutions (emergency shut down) in storage of oil and refined products / hot cracking gas / flare gas / blocking pumps
Petrochemicals - embedding propylene plant equipment / oxygen & hydrogen / ethylene cracking plants / PSA & molecular sieves switching valves / flare Isolation / CO2 / butadiene & styrene plants
Offshore - fire extinguishing systems / CO2 switching valves / crude oil insulation
Energy - steam / condensate / boiler feed water / in-blocking pumps / fuel gas
Pulp & Paper -lime & slurries / steam / boiler feed water / green, red & black liquor
Food - hot water / steam / condensate
Chemistry - syngas / nitrogen / acids
Steel industry - hot water / steam / condensate / blast furnace gas / cooking gas / oxygen / hot air / cooling water
