Table tube valve
The process and instrument line are combined on the same valve body
1/4 NPT female thread standard release port
1/2 NPT female thread standard export
Isolate the release valve set
Pressure equal volume refer to ASME B16.34
Handle colors have functional partitions
Ball valve and needle valve diversity combination structure
Material traceability
Each valve is factory tested in accordance with EN 12266 or API Std 598
Flange ports may be selected in accordance with ASME B16.5, EN 1092-1
The release port has a plug
Compared with traditional design, it saves weight, space and cost
Ball valve characteristics
The highest stress level is Class2500
Operating temperature :-54℃ to 232℃ (-65°F to 450°F)
Quarter turn open and close operation
The pointing block shows the open or closed position
Bottom load stem structure to prevent stem out, improve system safety
High strength stem bearing support provides smooth opening and closing and eliminates friction between stem and body
Valve packing may need to be adjusted during service
SMYTIK ball valves are designed for use in fully open or fully closed positions
Needle valve characteristics
The highest pressure level is Class4500
PTFE packing :-54℃ to 232℃ (-65°F to 450°F)
Graphite packing :-54℃ to 649℃ (-65°F to 1200°F)
Two stem stem design:
The upper valve stem thread is hardened by rolling and the lower valve stem surface is specially hardened
The grease on the upper stem threads is isolated from the system medium
The non-rotating lower stem up and down movement replaces the rotary lift, avoiding friction between the seat sealing surface and the valve head, and greatly reducing friction between the lower stem and the packing
The valve stem has the back sealing function in the fully open position. The handle is locked by screws at both ends, which is stable and durable
OS&Y needle structure
The highest pressure level is Class4500
PTFE packing :-54℃ to 232℃ (-65°F to 450°F)
Graphite packing :-54℃ to 649℃ (-65°F to 1200°F)
Two stem stem design:
The upper valve stem thread is rolled and hardened, and the lower valve stem surface is isolated from the system medium by the grease specially hardened upper valve stem thread
Non-rotating lower stem up and down movement instead of rotary lifting, avoid seat sealing surface and valve head friction, and greatly reduce the friction between the lower stem and packing valve cap bolt connection, good strength, high reliability
The valve stem has the function of back sealing, and can prevent the valve stem from being blown out by the medium pressure adjustable packing gland easy to adjust the packing gland to form an effective seal unibody forged valve cap bracket high strength, and ensure that the valve stem completely concentric handle with two screws locking, durable
