Design specifications：
Design and manufacture: ASME B16.34
Face to face: ASME B16.10
End Connection dimensions: ASME B16.25
Pressure-Temperature: ASME B16.34

Test and Inspection: API 598

Leak testing by helium mass spectrometry: API 602 MSS SP-117

Application: For ultra-high temperature molten salt media.

Design features：
1: Multi-layer seal design to ensure zero leakage:.

First seal: bellows assembly seal with built-in design and flush-free construction that guarantee the service life.

The second seal: the use of ultra-high temperature special low leakage filler (vermiculite), completely unaffected by oxidation.

This increases reliability, safety and high temperature resistance.

2: Threaded connection of the valve body and cover + welding,

double guarantee of strength and sealing.
3: The bellows is made of special material Inconel 625
4: The middle flange is grooved and the winding gasket is fully

positioned to prevent gasket extrusion damage.
5: Sealing surface characteristics: one-piece valve seat, line sealing,

overall overlay carbide. Conical sealing, removal of crystalline molten salt.
