定义
A specialized mounting pad designed to provide a secure, vibration-resistant interface between an actuator and a high-pressure ammonia flow control valve body. It ensures proper alignment, maintains seal integrity under extreme pressure differentials, and facilitates torque transmission for valve positioning.
工作原理
The pad acts as a structural adapter that distributes mounting forces evenly across the valve body while maintaining precise actuator alignment. It incorporates sealing surfaces and bolt patterns that match both the actuator base and valve flange specifications, preventing leaks and misalignment under operational stresses.
材料
Stainless steel 316L or duplex stainless steel 2205 for corrosion resistance against ammoniamay include PTFE or graphite gasket layers for sealing.
Surface Finish
Ra ≤ 3.2 μm on sealing faces
Pressure Rating
PN40/Class 300 minimum
Temperature Range
-40°C to +150°C
Mounting Thickness
12-25 mm
Bolt Circle Diameter
ISO 5211 standard (e.g., F10/F12/F14)
标准
ISO 5211DIN 3337ASME B16.5

常见问题

Why is material selection critical for ammonia valve mounting pads?

Ammonia is highly corrosive and can cause stress corrosion cracking in unsuitable materials. Stainless steel 316L or duplex grades provide necessary resistance to ensure long-term reliability and prevent catastrophic failure.

Can mounting pads be interchanged between different valve manufacturers?

Only when they conform to the same ISO 5211 mounting standard dimensions and pressure ratings. Manufacturer-specific designs may require custom pads for proper compatibility.
