Ball Valves, SRI, ValvesMultiway Type
SRi multiways ball valve can be made, on demand, with L-port, T-port or X-port. Ball valve can be designed as transflow or non-transflow. The non-transflow avoids connection of 3 or 4 branches during stroke. The SRi multiways ball valve keeps the valve tight even if the automatic cavity relief by seat leakage is actived.

Ball Valves, SRIPig Launcher
SRi Pig Launcher (or receiver) is safe and much more compact than a pig trap.
Manual or automatic secured access door.
The pig launcher can be equipped with an optional by-pass to allow flow between both sides of the valve if the pig is presented in the valve ball.

Butterfly Valves, Solent & Pratt, ValvesR-Series: Resilient Seat Butterfly Valve
Resilient Sealed Valves are suitable for isolation and flow control applications and have a proven record for reliability over the past 40 years for application in hydrocarbon service, seawater cooling systems, offshore. Proven record of reliability onshore and marine fire mains systems, desalination plants and power plant installations. The ease and flexibility of material selection enables both simple and arduous applications alike to be within the capability of this valve series. Valves can be supplied with manual, electric, pneumatic or hydraulic operator. Fail-safe systems for emergency operation are also available.
-
Ball Valves, SRI, ValvesSide Entry
The side-entry ball valve is the most common and popular design. Given its great modularity, SRi can manufacture any side-entry ball valves with special options. In case of maintenance operation, all parts of the valve can be replaced, so valve lifetime is extended.

Butterfly Valves, Solent & Pratt, ValvesT-Series: PTFE Sealed Firesafe Butterfly Valve
This single piece construction also provides a rigid assembly when pinned to the disc via means of shaft pins (peened over and locked). This prevents excessive disc deflections, which maintains a constant disc/seal contact stress ensuring a bi-directional sealing valve at both low and high pressures. The valve has a double offset design providing a camming action. This eliminates excessive wear between the seat and disc-sealing interface both during the opening and closing strokes extending the sealing life of the valve. Maintenance of the valve is quick and relatively simple. The PTFE insert, seat gasket and secondary seat can be replaced by simply unbolting the retaining ring and assembling the new parts without removing any other parts. Gland packing is simply adjusted by tightening gland nuts, which are easily accessible between the mounting legs without having to remove the adapter plate or actuator.
-
Ball Valves, SRI, ValvesTandem Type
SRI tandem ball valve is constituted by two balls, like the Double Black and Bleed ball valve, but the face-to-face dimension is in accordance with ASME B16.10. On site, a SRI tandem ball valve can replace a single ball valve without modification to the pipe meaning two ball valves instead of only one.
-
Ball Valves, SRI, ValvesTop Entry
The cover of the top-entry ball valve can be disassembled from the body of the valve, so all parts can be easily maintained or replaced in-line. On demand, trim, trunnnion and ball can be made as a monobloc piece. This option increases the reliability of the valve. This construction allows more flexibility in customization of driving train design, allowing for example the mounting of actuator directly on the bonnet without an intermediary bracket

Butterfly Valves, Solent & Pratt, ValvesTOSV – Triple Offset segment Butterfly Valve
Utilizing the latest computer aided design systems and software Solent & Pratt enables special design requirements, dimensions and specifications to be accommodated. The TOSV™ series valves are of dedicated Triple Offset * geometry design. This particular feature eliminates the disc-to-seat rubbing condition, normally associated with ‘HPBV’ butterfly valves, which induces wear of varying degrees, even in metal seated versions. This is an ideal replacement valve for Ball, Plug or Gate types Standard TOSV design features include zero leakage with bi-directional shut off to API 598, a field replaceable seat and seal ring for reduced maintenance costs, non-galling design to enable a wide variety of material options, with options for live loaded packing and arduous duty bearing protectors.

Butterfly Valves, Solent & Pratt, ValvesTOSV Double Block & Bleed Valve
As safety and environmental issues have become of greater concern to mankind, the need for assured valve shut off providing absolute and verifiable isolation are regularly becoming the standard specification for critical applications. Typical areas of application include offshore and onshore petrochemical production including, gas injection, water injection, oil and gas transmission lines including airport fuelling facilities and other areas where flammable and toxic emissions are unacceptable.

Ball Valves, SRI, ValvesWafer Type
Wafer ball valves saves space and weight thanks to the absence of flanges – The design allows replacement of a gate valve without modification of the piping should a reduced bore be considered.
