- Bonnet has an integral flange that accepts hammer nut force when making the bonnet-to-body connection. There are no snap rings subject to possible failure in sour service or in atmospheric corrosion.
- Micro-Form trim is standard for throttling or on/off service at no extra cost.
- Choices of port diameters up to 31.8 mm (1.25 in), end connections, and trim materials suit these valves to many applications, including sour service.
