Tested Standards

Solent & Pratt utilizes the latest computer aided design systems and software enabling special design requirements, dimensions and specification to be accommodated. Valves are built and tested to the following standards:

• Quality assurance: Certified by Lloyds to ISO 9001
• Valve design: ANSI B16.34
• Fire test: API 607 4th edition, BS 6755 Part 2 and API 6FA
• Face to face: ANSI B16.10
• Flange ANSI B16.5 (3” to 24”), ANSI B16.47 (28” and larger)
• Testing: BS 6755 Rate A, API 598, API 6D

Material Range
Valve design range is available in most other materials

• 316 stainless steel
• Duplex stainless steels
• 6 Mo stainless steel
• Bronze
• Monel
• Incoloy
• Hastelloy B and C
• Titanium
• Zirconium

Patented two direction valve geometry

The Solent & Pratt Triple Offset Segment Valve utilizes the well established patented valve geometry where the shaft is offset from the body in two directions (1) and (2), whilst the disc is a segment taken from a cone where the apex is offset from the center line of the valve (3). The disc (segment) of the valve houses a field replaceable metal laminate seal whilst the field replaceable seat ring is housed in the body of the valve.

Due to the valve geometry there is no interference or rubbing between seat and seal as the valve strokes through it’s full 90°.

Feature	Description
Replaceable seat and seal	Triple Offset Geometry with field replaceable seat and seal rings (patent design)
Zero leakage	Bi-directional shut-off to API 598, zero leakage capability
Resilient metal seat	Torque generated resilient metal sealing provides repeatable long term sealing performance
Firesafe	The valve design range is certified firesafe to BS 6755 : Part 2 and API 6FA : API 607 4th edition
Steam Jacket	Integral steam jackets are available on the double flanged body design
Face-to-face	TOGV is available with face-to-face to ANSI B16.10 enabling easy replacement of ball, plug and gate valves
Ease of material selection	No galling is possible with this design making material selection simple
Sizes:	3” (80mm) to 24” (600mm). Temperature range to up to 1292°F (700°C)
Pressure Ratings	ANSI 150 through 300 Ib.
Torque	Under high pressure (14.5Bar/210psi) the torque required to operate the valve was 160 N.M
Seal Temperature	During test burn period, where temperatures reached 1652°F (900°C) the high integrity metal/metal seal still ensured tight shut off
Bearing Protector	Enables arduous duty applications where solids may be present in the flow media.
Live Loaded Packing	A set of Belleville spring washers fitted to the gland follower provides automatic adjustment to packing.
Steam Jackert	integral steam jackets are available on the double flanged body design
Latern Ring	Available for the packing box
Ease of actuation	Rotary action of the valve enables ease of actuation and suitability for either control or isolation
Superior gland performance	Rotary motion valves greatly reduce fugitive emissions from gland packing. In addition gland packing life is considerably improved
