1.?The connection flanges between body and bonnet strictly calculated based on ASME standard.

2.?Stronger, leakproof bolted body bonnet joint ensures joint tightness with a higher bolting torque.?

3.?The parallel slide valve design relies on the primary system pressure acting on the downstream disc for seat integrity.

4 .There is no wedging action or extra loading on the seats. Due to its inherent design, the parallel slide valve is not subject to thermal binding concerns, resulting in a distinct safety advantage in high temperature service.

5.?Body – superior strength forgings / high quality castings.

6.?Live-loaded bonnet bolting?stores the required sealing load during a pressure or temperature induced transient which cause bonnet movement.

7.?Unique parallel slide forged cage unit design comprises all operating parts of the slide discs and is precision guided to?provide longer disc, seat, and body life.

8.?Hardfaced seating faces resist erosion.

9.?Non-rotating stem requires lower operating torque.

10.?Bypass valves?are recommended to equalize pressure across the disc before opening if the valve is exposed to very high differential pressure.

11. TH-Valve Nantong?offers equalizing and bypass pipes and valves in many different configurations to help ensure the valve will open under any operating conditions, preventing over pressurization, pressure locking, and thermal binding.

12.?Optional live-loading of packing extends low emission service life especially in service with large pressure/temperature transients or frequent cycling.
