FAQ
What media and operating conditions is the HP114-K3 high-performance butterfly valve suitable for?
The HP114-K3 is a double eccentric valve for on/off and control duty with gases or liquids. Its operating temperature range is -60°C to +600°C; for vacuum service, it goes down to 1 mbar absolute. The actual applicable range must also be matched to the selected sealing system, valve size and pressure class.
How to choose between the R-PTFE soft seat and the Inconel metal seat for the HP114-K3?
The R-PTFE soft seat has a maximum operating temperature of 230°C and a leakage class of EN 12266 Leakage Rate A; the Inconel metal seat has a maximum operating temperature of 600°C and its sealing performance complies with EN 12266 Leakage Rate B and ISO 5208 Category 3. For higher temperatures, the Inconel metal seat can be selected based on the upper temperature limit; the final choice should also be confirmed against the media, pressure and sealing requirements.
What is the maximum operating pressure of the HP114-K3 at different valve sizes?
For nominal diameters up to DN150, the maximum operating pressure of the HP114-K3 is 40 bar; for nominal diameters above DN150, it is 25 bar. The standard size range of the valve is DN50 to DN600; larger sizes must be confirmed based on actual requirements.
Which flange standards and actuator interfaces can the HP114-K3 be combined with?
The valve flange connection is available with EN 1092 PN10, PN16, PN25 and some PN40 ratings, with PN40 applicable up to DN150; DN200 to DN600 can be matched with EN 1092 PN10, PN16, PN25. ASME Class 150/300 and AS 4087 PN16/21 connections are also available. Flange sealing faces include EN 1092 Form A/B, ASME RF and FF; the top flange complies with EN ISO 5211.
Does the HP114-K3 offer a fire-safe design and suitability for high-frequency operation?
The PTFE/Inconel fire-safe design of the HP114-K3 is rated for temperatures up to 200°C and complies with BS 6755 Part 2 and API 607 5th Edition. The valve is rated as maintenance-free and is suitable for long-term use under high-frequency operation.
