708SH COMPACT FLOW CONTROL VALVE

Fractional Flow Control Valve in Three Way Control Design

The Mark 708SH was developed to provide the most accurate control available for fractional flow services; whether for pilot plant installations, test stands, R&D facilities or for specialised processes such as dosing, injection and venting applications. The Short Pattern, 1/4" offers Cv's ranging from 0.00001 through 0.2 (0.000009 to 0.17 Kv in DN8). A small package ideal for critical fractional flow applications where space is at a premium.

Features & Benefits:

• Rolling diaphragm design for effective, constant area control regardless of stem position
• Spring-loaded packing maintains proper compression whilst minimising excessive friction
• The bolting provides solid construction and secure tight connections

Technical Specifications:

• Sizes: 1/4? (DN8)
• End Connections: Threaded (NPT, BSPT, BSPP), Socket Weld and others
• Body Materials: Carbon Steel, Stainless Steel, Hastelloy C, Monel, Alloy 20, others
• Diaphragm Materials: 7M & 14M - rolling (Nylon/Nitrile)

LowFlow control valves and regulators are often used in OEM, laboratory or pilot plant applications for critical control of gases, liquids or steam. Installations such as these frequently require valve trim changes and a multitude of CVs in order to meet varying flow requirements for a given application.
