Application scenarios
Vacuum and Low-Pressure System Applications
The HP114-E can be used for on/off and modulating control of gases or liquids in vacuum or low-pressure piping systems. Its vacuum capability extends down to an absolute pressure of 1mbar, with the corresponding low-leakage performance available according to the seating configuration.
Selection points
Double-Offset Design
The valve features a double-offset design, which can be considered as a structural configuration criterion during selection.
R-PTFE and Inconel Seating Systems
The valve is available with R-PTFE soft seating or Inconel metal seating. R-PTFE soft seating is suitable for temperatures up to 230°C and provides Leakage rate A according to EN 12266. Inconel metal seating is suitable for temperatures up to 450°C and provides Leakage rate B according to EN 12266 and Category 3 according to ISO 5208.
Multiple Face-to-Face Dimension Standards and Actuator Mounting Interface
The face-to-face dimensions comply with EN 558 Series 20, ISO 5752 Series 20, and API 609 Table 1. The actuator mounting flange complies with EN ISO 5211, providing a basis for matching piping dimensions and actuator interfaces during selection.
Vacuum Service Capability
The valve can be used for vacuum applications down to an absolute pressure of 1mbar.
Fire-Safe Seating Configuration
A PTFE/Inconel fire-safe seating configuration is available for temperatures up to 200°C and complies with BS 6755 Part 2 and the 5th Edition of API 607.
FAQ
Which media and control duties are suitable for the HP114-E high-performance butterfly valve?
The HP114-E can be used for on/off or modulating control of gas or liquid media and features a double-offset design. Selection should consider the properties of the medium, operating temperature, pressure, and required leakage class to determine the appropriate seating system.
How should users choose between R-PTFE soft seating and Inconel metal seating for the HP114-E?
R-PTFE soft seating is suitable for temperatures up to 230°C and complies with Leakage rate A according to EN 12266. Inconel metal seating is suitable for temperatures up to 450°C and complies with Leakage rate B according to EN 12266 and Category 3 according to ISO 5208. For applications requiring higher temperatures, Inconel metal seating should be evaluated first. For applications requiring a higher seating performance at temperatures not exceeding 230°C, R-PTFE soft seating may be evaluated.
Can the HP114-E be used for fire-safe and high-temperature applications?
The valve can be supplied with a PTFE/Inconel fire-safe seating configuration for operating temperatures up to 200°C, complying with BS 6755 Part 2 and the 5th Edition of API 607. The Inconel metal-seated version supports operating temperatures up to 450°C. However, the applicable temperature ranges for the fire-safe and standard metal-seated versions differ and should be selected according to the actual service conditions.
Which standards apply to the HP114-E installation interfaces and structural dimensions?
The valve is available in nominal sizes from DN 50 to DN 200. Its face-to-face dimensions comply with EN 558 Series 20, ISO 5752 Series 20, and API 609 Table 1. The connection flanges can accommodate EN 1092 PN 10/16, ASME Class 150, and AS 4087 PN 16/21. The flange facings are compatible with EN 1092 Form A/B and ASME RF and FF. The actuator mounting flange complies with EN ISO 5211.
Can the HP114-E be used in vacuum systems, and how is the operating pressure confirmed?
The HP114-E can be used for vacuum service down to an absolute pressure of 1mbar. The valve operating pressure must be confirmed using the applicable temperature-pressure curve, because the permissible operating pressure varies with the operating temperature and seating configuration.
