8 BOLT UNIONS & COMPANION FLANGES

These 4 bolt unions can be used anywhere system piping needs to be joined together between shut off valves. Using piping unions such as these significantly improves the ease by which maintenance can be performed particularly where long runs or multiple directional changes are necessary. Our flange unions feature a captured o-ring design, hardened mounting bolts, and are available in NTP or Socket Weld configurations. Suitable for use in mobile or stationary applications.

FEATURES:

High Flow BYPASS VALVES

ME840-16/125

These bypass valves are specifically designed to protect truck and plant pumps from damage due to excessive pressure while providing the industry’s best bypass flow rates across a full range of set pressures. They feature wide open flow channels with an orifice weep hole chamber to prevent the valve from slamming open / closed. The weep hole chamber also helps prevent valve seat chatter by allowing constant pressure communication between both the upstream and downstream side of the seat.

FEATURES:

TURBO-FLO LE DRY BREAK TRANSFER SYSTEMS

ME808-16

FOR USE WITH LPG & NH3 TRANSFER SYSTEMS

The ME808-16 Series valves feature our new modular Excela-Flange 4-bolt inlet flange design that can be easily adapted to both NTP thread or socket weld type A companion flanges (ME840 & ME841 Series) ranging from 1-1/4" to 2" in diameter making it universal to piping sizes within this range. This innovative system allows installers the ability to eliminate unnecessary connections as well as possible leak points by integrating a convenient 4 bolt flange union at the valve inlet. The Turbo-Flo LE system provides a safe, ergonomic and efficient solution for liquid or vapor transfer applications while increasing productivity and dramatically reducing fugitive product emissions. For use with bobtail, transport, railcar and bulk plant applications.

FEATURES:

1-1/4” MNPT X 4 BOLT FLANGE INTERNAL VALVE

ME991-10

The ME991-10 Series valves feature our new modular Excel-Flange 4 bolt outlet flange design that can be easily adapted to both NTP thread or socket weld type B companion flanges (ME842 & ME843 Series) ranging from 1-1/4” to 2” in diameter making it universal to piping sizes within this range. This innovative system allows installers the ability to eliminate unnecessary connections as well as possible leak points by integrating a convenient 4 bolt flange union at the valve outlet. Intended for use on bobtail trucks and storage tanks with 1-1/4” threaded connections in directional or bi-directional flow applications. Provides both manual shut-down as well as excess flow closing in the event of the piping being separated from the valve. Can be equipped with manual latch, pneumatic or rotary actuator, open/ closing devices. All valve models are equipped with a break-away feature in the cast body which permits the piping to shear off in the event of side impact, leaving the valve poppet intact and protecting the tank from catastrophic product loss. For liquid or vapor service applications.

FEATURES:

High Flow GLOBE AND ANGLE VALVES

The ME813, ME818, ME819 and ME823 Series valves feature our new modular Excela-Flange 4 Bolt inlet/outlet design that can be easily adapted to both NTP thread or socket weld type A companion flanges (ME840 & ME841 Series) ranging from 1-1/4” to 2” in diameter making it universal to piping sizes within this range. This innovative system allows installers the ability to eliminate unnecessary connections as well as possible leak points by integrating a convenient 4 bolt flange union at the valve inlet/ outlet connections.

FEATURES:

High Flow BACK CHECK VALVES

The ME873S Series valves feature our new modular Excela flange 4 bolt inlet flange design that can be easily adapted to both NPT thread or socket weld type B companion flanges ranging from 1-1/4” to 2” in diameter making it universal to piping sizes within this range. This innovative system allows installers the ability to eliminate unnecessary extra connections as well as possible leak points by integrating a convenient 4 bolt flange union at the valve inlet. Marshall Excelsior High Flow back check valves provide back flow protection to container openings or liquid lines where flow is intended for one direction. The valve is normally held closed until pressure activates the valve when flow is directed into piping or containers causing the back check to open. When flow stops or reverses, the check returns to the closed position. All MEC High Flow Back Check valves are supplied with o-ring so seats, which can be removed for metal to metal seating. Also available with permanently bonded on main valve seals (SBN).

FEATURES:

VALVE INSTALLATION TOOL

MEP873

The MEP873 is intended to fit all Excela-Flange type A flange tank valves. This tool is designed to fit snuggly into each of the 4 type A smooth bore flange bolt holes with individual posts. Each replaceable post features a self-retaining spring ac on ball detent to hold the tool firmly in palce while attached to the Excela-Flange valve and has rubber cushioning pads to prevent direct contact with sealing surfaces. The MEP873 features a robust 1” square socket drive for use with even the most heavy-duty impact or socket wrenches.

SOCKET WELD BACK CHECK VALVE

ME870SW-16

These Excela-Flange High Flow Socket Weld Back Check valves lead the industry with up to 20% More Flow than the nearest competitor. Back check valves provide flow protection to container openings or liquid lines where flow is intended for one direction. The valve is normally closed until pressure activates the valve when flow is directed into piping or containers causing the back check to open. When flow stops or reverses, the check returns to the closed position.

Being socket weld connection points, these valves are ideally suited for inline applications where welded piping construction is desired, such as in a bobtail spray fill / bypass return combination line. A perfect companion to the MEC Excela-Flange product line. Only available with metal-to-metal seat due to high heat associated with socket weld construction/installation.
