Application scenarios
Tank truck loading/unloading line shut-off
Used in DN 80 or DN 100 tank truck loading and unloading lines with DIN 28459 tank truck flanges, serving as a shut-off and line isolation valve during media loading and unloading.
Selection points
DIN 28459 tank truck flange connection
The TW80/TW100 uses the DIN 28459 tank truck flange standard, with ASME RF and FF sealing face options, suitable for connection scenarios that need to match the corresponding tank truck interfaces.
Aluminum body with stainless steel disc
The body is made of aluminum alloy and the disc of G-X6CrNiMo18-10 stainless steel, suitable for selection scenarios where valve material configuration and equipment weight are a concern.
Multiple sealing materials and temperature range options
EPDM, NBR, FPM, PTFE, and SBR-green sealing materials are available; the operating temperature range is -20°C to +160°C, with the applicable range depending on pressure and media.
Two-piece body with PTFE seal
A two-piece GK-AlSi12(Cu) body with PTFE seal is available as a construction option; body construction and sealing material should be confirmed together during selection.
Triple bushings and maintenance-free design
The valve features triple bushings and a maintenance-free design, suitable for selection scenarios that require reduced routine maintenance.
FAQ
Which pipe connection specifications is the TW80/TW100 wafer butterfly valve suitable for?
The TW80/TW100 is available in DN 80 and DN 100 nominal sizes. The connection flange complies with the DIN 28459 tank truck flange standard, and the flange sealing faces are available in DIN 28459, ASME RF, and FF forms. The nominal pipe size, flange standard, and sealing face form should be verified during selection.
What are the pressure and temperature ratings of the TW80/TW100?
The valve has a maximum operating pressure of 6 bar and an operating temperature range of -20°C to +160°C. The actual permitted operating conditions depend on the media and pressure and should be confirmed against the specific media, pressure, and temperature.
Which sealing materials are available for the TW80/TW100, and how should they be selected?
Available sealing materials include EPDM, NBR, FPM, PTFE, and SBR-green. The sealing material should be selected based on the conveyed media, operating temperature, pressure, and sealing compatibility; the currently available documentation does not list the media compatibility of each sealing material, so this must be confirmed according to the actual model and application conditions.
Which sealing performance standards does the TW80/TW100 comply with?
The sealing class of the TW80/TW100 complies with EN 12266 Leakage rate A and ISO 5208 Category 3. This information can serve as a basis when verifying the valve shut-off sealing class for a project.
What are the maintenance and material construction features of the TW80/TW100?
The series features a triple bushing design, with maintenance-free and dismountable construction, and recyclable materials. The disc is made of stainless steel G-X6CrNiMo18-10 (1.4408); the body is available in a one-piece GD-AlSi9Cu3 (3.2163) version and a two-piece GK-AlSi12(Cu) (3.2583.02, with PTFE seal) version.
