Linear and equal percentage flow characteristics are available with Cv’s ranging from 0.05 (0,04 Kv) to 1.25 (1,1 Kv).
In addition, the Mark 708HPA is available in a variety of end connections and optional materials of construction making it a versatile solution to your most demanding valve requirements.
Features- Union Style Body / Bonnet Connection - provides solid construction and secure connection. The metal ‘C’ ring gasket provides excellent sealing without exposing the bonnet threads to the media. Adds ease to maintenance , as bonnet and actuator assembly may be removed with the body in-line.
- Mechanically Loaded PTFE Chevron Heavy Duty V Ring Packing - the adjustable packing arrangement maintains a proper compression, while minimizing excessive friction. The PTFE packing is suitable for temperature to 450° (232°C), while mechanically loaded Graphoil may be used for higher temperature requirements.
- Rolling Diaphragm - the rolling diaphragm design ensures that the effective diaphragm area remains relatively constant, regardless of valve stem position. This increases accuracy of the actuator while positioning the valve by ensuring a linear response to input signal changes.
- Guided Trim - extended orifice and plug guiding are standard and offers improved shutoff and accuracy.
- Standard with side mount positioned.
