The Flowserve Edward Univalve® Stop Valve is small bore with a forged body and body guided disc. This globe valve features several aspects and characteristics that allow it to work efficiently and correctly in several different industries and applications. These aspects include:

• Ease of disassembly due to ACME threads in the stem and the threaded bonnet 
• Resists wear due to the stem being hardened and ground to a fine finish
• Reduced torque and eliminated galling because the material in the yoke bushing has a low coefficient of friction
• Faster in-line internal repairs because the two piece yoke-bonnet assembly can be disassembled
• Minimized flow direction changes and reduced pressure drop due to an inclined stem construction with an optimum flow shape
• Eliminated stem bending from the use of anti-thrust rings in the body guided disc
• Long seat life provided by an integral hardsurfaced seat
• Sure grip, even when wearing gloves, because the handwheel is rugged and knobbed on smaller valves. Larger, high pressure valves have many times the closing force of an ordinary handwheel due to an impactor handle or handwheel. 
• Dependable sealing on unwelded models due to the utilization of a graphitic gasket. Welded models employ a fillet weld (canopy weld on stainless steel valves) for absolute protection from body-bonnet leakage. 
• Optimum seal ability and life from the use of flexible packing material with carbon fiber anti-extrusion rings
• Reliable bonnet seal because the bonnet seal ring is a die formed, flexible graphite gasket seated to a prescribed bonnet torque
• Positive shutoff and leak protection provided by a secondary stem seal back up on the integral backseat

Available in class 1690, 2680 and 4500 from sizes 1/2 to 4 inches.
