• The innovative dual-plate design employs two spring-loaded plates suspended on a central vertical hinge as flow begins, the plates open in response to a resultant force Which acts at the center of the sealed surface area

• The contact point of the reacting spring leg's force acts beyond the center of the plate area,causing the heel to pen first.This prevents rubbing of the seal surface prior to normal plate opening

• As the velocity of flow decreases, torsion spring action reacts automatically. The moves of plates closer to the body seats, reducing the distance and time of travel for closure. By Having the plates closer to the body seats at the time of flow reversal.the valve dynamic response is greatly enhanced.This dramatically reduces the water hammer effect

• At closing, the point of spring force causes the plates to close first. This prevents dragging of the heels of the plates and periods maintains seal integrity for much longer periods

We test leakage of each roll before braiding, then we cut 300mm and crimp it to test
burst pressure after brading.

We use CNC Lathes Machine for end fittings production. Machine system, knife and inspection
tools are all imported from Japan.

We use Techmaflex Crimping Machine which is imported from France. This machine has
