Dixon Valve & Coupling
Hydraulic Coupling: V-Series MIL-C-51234 Valved Coupler (Male Threads)

General purpose hydraulic quick-connect provides superior flow characteristics for a variety of applications.

Quantity

Specifications for Variant SKU: 4VM4-B Dixon
Series:	V-Series
Shape (Orientation):	Straight
Ends Configuration:	1/2in Female V-Series QD Interchange, 1/2in Male NPTF
Material(s):	Brass
Seal Material(s):	Buna-N/Nitrile Rubber

Compatibility & Interchange:	Interchangeable to MIL-C-51234 Interchangeable with Snap-Tite H/IH Series and Faster TNV
Construction:	Machined components are manufactured using solid bar stock. Stainless steel balls, retaining rings and springs maximize corrosion resistance and extend service life. Steel componentry is plated using ROHS Compliant Trivalent Chrome. Steel coupler sleeves are hardened to resist deformation and maximize service life.
Seal Components:	Nitrile seals are standard, providing a temperature range of -40°F to 250°F (-40°C to 121°C). All couplers incorporate a PTFE anti-extrusion ring to protect the seal components from dynamic impulse damage. 1/4" to 1" valve seals are crimped in place to maintain integrity during excessive flow conditions and pressurized connection. 1-1/4" to 2" valve O-rings are retained by a unique seal-groove profile and are field replaceable.
Additional Information:	For a selection guide, cross reference tables, safety info, fluid compatibility, and other general info, please see: Dixon Valve Quick Disconnect Guide.PDF

Minimum burst pressure ratings were established under laboratory conditions using a Static Burst Unit (SBU). For high impulse applications and to meet Det Norske Veritas (DNV) compliance, the burst pressure must be divided by four (4) to ensure a 4:1 safety factor during system operation.
