TOPAZ

TOPAZ - top-of-the-range universal valve for strength

, versatility, very high quality and resistance

The TOPAZ series is undoubtedly the spearhead of Enolgas Bonomi S.p.A. industrial valves. It is about a series of double flange (split-body) valves typically used in industrial and plant engineering applications, in different sectors such as: chemical, food, oil sector etc.
The durability and versatility makes it a universal product, suitable for those customers who want to focus on products of the highest quality and resistance. The gauge and the pressure class is regulated by the DIN standard and allows a perfect fit interchangeability with products from other manufacturers. 
The production is available in stainless steel (AISI316) and in carbon steel (LF2). The TOPAZ series is characterised by the lateral seal in PTFE (on request in other special materials); upper seal in PTFE and with O-ring; antistatic device; anti-burst pin; threaded holes; body from bar. 
The particular coupling between the PTFE gasket and the O-ring at the level of the valve pin, makes the same very soft in its opening and closing manoeuvres, as well as ensuring a high seal even in more severe application conditions.

All valves are tested and verified before sale and are guaranteed 2 years.
