Durco Sleeveline ®;
•Non lubricated
• Tapered plug/PTFE sleeve primary seal
• Static/self-adjusting dynamic stem seal with the unique TM/PFA reverse lip diaphragm
• Quick thru-line seal adjustment with the valve in-line and under pressure
• Bi-directional flow
• ASME (ANSI) Class 150 and 300
• Optional 3-way
• Available with TMHT seat for high temperature services

Durco G4 Sleeved Plug
• Sizes available in 1/2″ (15mm) – 20″ (500mm)
• Large PTFE sleeve seal area offers positive shut-off and extended service life Double D plug stem accepts most standard actuation equipment. Splined shaft is used on larger sizes
• Actuator mounting pads are standard on the flanges for solid support

Durco G4Z Fire Sealed
•Stem seal consists of Grafoil packing, metal diaphragm, TM/PFA diaphragm and Grafoil gasket
•Grafoil packing rings at the stem and Grafoil gaskets at the top cap reduce atmospheric leakage to a negligible amount should fire destroy the PTFE sleeve and diaphragm
•Vented plug accommodates the forces of fluid thermal expansion

Durco G4BZ-HF Alkylation
• Stem seal consists of Grafoil packing, Monel diaphragm, PFA diaphragm and Grafoil gasket
• Grafoil packing rings at the stem and Grafoil gaskets at the top cap reduce atmospheric leakage to a negligible amount should fire destroy the PTFE sleeve and diaphragm
• Quarter-turn operation can be cost effectively actuated with rotary actuators

Durco G4B Marathon™
• Specifically designed for reliable performance in high cycle on-off or modulating services
• Fugitive emissions containment often equals that of more expensive, severe or toxic service valves
• Highly polished sealing surfaces eliminate wear and enhance seal integrity

Durco TSG4 Severe Service
• Meets/exceeds CAA fugitive emissions regulations at one-third to one-half the cost of bellows sealed valves
• Lantern rings (optional) for continuous monitoring, inert gas pad or insertion of process compatible lubricants
• Drilled and vented plug balances pressure between plug port and body cavity

Durco Mach 1™ High Performance
• In-line plug adjustment under pressure stops thru-line leakage
• Easy seat replacement with valve in-line; no special tools required
• PFA reverse lip diaphragm provides dynamic and static, self-adjusting stem seal
• Alloy diaphragm provides stem seal reinforcement

Durco G4 V-Port Control
 In addition to the features and benefits that have made Sleeveline the process industry’s premier plug valve, Flowserve offers the G4 V-Port valve for precise modulating control services. Durco G4 V-Port control valves are available in a variety of trim configurations to satisfy a user’s flow control needs.

Durco Full Port Plug
• Full round port plug valves are designed to offer low differential pressure which will result in energy savings
• Full port valves are ideal for emergency dump systems as they offer the lowest possible resistance to flow
• Tapered plug design allows re-seating of the plug in the event of excessive wear.
• In-line adjustability allows for easy maintenance.

Durco TX3 Triple Offset Butterfly Valve
• High performance triple offset butterfly valve
• Capable of zero leakage with laminated seal rings
• ASME Class 150-600, other pressure classes available
• High temperature and Cryogenic configurations upon request

Durco BX 2001 High Performance
• Large diameter, one-piece high strength shaft reduces deflection for positive, repeatable shut-off at higher ∆P than similar valves
• PolyLube® bearings or optional severe service bearings both offer low torque and high-cycle life
• Independent packing set adjustment prevents stem seal emissions

Durco BTV 2000™ Lined Butterfly
• Unequaled performance in high temperature/high cycle services

Durco T4E Plug
• Large port areas assure low pressure drop and higher Cv (Kv)
• V-port plugs available for modulating control (1 in [25 mm] thru 4 in [100 mm])
• ISO 5211 mounting pad

Durco T4E V-Port Plug
• Offers precise modulating control
• Can be used in a wide range of corrosive applications
• T4E V-port control valves are available in a wide variety of trims to satisfy the user’s exact flow control needs.
• Available with full open Cv values of 0.75 to 187 (Kv 0.65 to 161)
