FAQ
Which media and control tasks is the HP111 high performance butterfly valve suitable for?
The HP111 is suitable for gas or liquid media and can be used for on/off control or modulating control of pipelines. Its double eccentric design is well suited to industrial valve applications that require both reliable open/close performance and modulating capability.
How to select between the R-PTFE soft seal, Inconel metal seal and the fire-safe version for the HP111?
The sealing system should be selected primarily based on the media, temperature and fire-safety requirements. The R-PTFE soft seal is rated up to 230°C with leakage class EN 12266 Leakage rate A; the Inconel metal seal is rated up to 600°C with leakage classes EN 12266 Leakage rate B and ISO 5208 Category 3; the fire-safe version uses a PTFE/Inconel seal combination, rated up to 200°C, and complies with the BS 6755 Part 2 and API 607 5th Edition fire-safe standards.
What are the pressure, size and vacuum application ranges of the HP111?
The HP111 covers nominal sizes from DN 50 to DN 1200, with Inconel metal-sealed versions available up to DN800 PN16. The maximum operating pressure is 40 bar for DN150 and below, and 25 bar above DN150; in vacuum service, it can be applied down to an absolute pressure of 1 mbar.
Which pipeline flanges and actuator mounting interfaces can the HP111 be combined with?
The valve's face-to-face dimensions conform to EN 558 Series 20, ISO 5752 Series 20 and API 609 Table 1, with EN 558 Series 25 available as an option. Flange connections can be adapted to standards such as EN 1092 PN 10/16/25/40, ASME Class 150 and AS 4087 PN 16/21, with flange sealing faces including EN 1092 Form A/B and ASME RF, FF; the top mounting interface conforms to EN ISO 5211.
Does the HP111 require frequent maintenance under high-frequency open/close duty?
The HP111 is maintenance-free by design; documentation states that it achieves a long service life even under high-frequency operation. A positioning bracket can be used to assist alignment during installation, and the selected size, pressure rating, sealing system and connection standards should be matched to the actual pipeline conditions.
