* The API 600 Gate Valves is exceptionally sturdy, rugged, and durable, with a reputation for quality, integrity, and long service. * They are designed for tight sealing and ease of operation. The valves are available flanged & butt-weld ends in pressure rating from ASME Class 150 to Class 2500, and in a variety of materials of construction. * Gate Valves are of flexible wedge design, outside screw and yoke, and bolted-bonnet construction. The valves conform to API 600. Main features * Bolted body-bonnet design,seal welded & Valves with pressure seal bonnet * Bellows-sealed Gate and Globe valves available * Bolted body-bonnet joints provided with spiral-wound stainless steel gasket and graphite filler for maximum protection against leaks * Die-formed graphite inner packing rings and braided graphite end rings with Inconel wire reinforcement and corrosion inhibitor * T-head stem-disc connection of gate valve fully meets strength requirements of API 602 and API 598 * Rolled ACME thread on stem for smooth operation Tapered shoulder on the stem for back seating * Self-aligning type gland assembly with stud-and-nut tightening * Integral hard-faced body seat for globe and check valves * Spring-loaded disc on check valves suitable for no horizontal applications too * Gate and globe valves can be offered with electrical actuators * Austenitic SS forging for body and bonnet of Cryogenic valves, resulting in excellent impact strength, minimal heat loss and resistance to corrosion * Valves can be offered to NACE MR-0175 and other special NACE requirements

1. Design and manufacture of product according to ANSI B16.34 and API600 and API 6D. 2. Compact structure, small bulk, perfect rigidity, safety and reliable. 3. Blow down part (disc) utilize flexible structure, can automatically compensate distortion of body due to abnormal burden or temperature,so seal reliable and prevent wedge disc being blocked. 4. Manual valve with size over or equal to NPS 10", class 150 pounds and size over or equal to NPS6", class 600~2500 pound equip with roller bearing to operate easily. 5. Material of main body. Material of trims, packing, washer, material of fastener can logically combine according to customers requirement or actual work status. 6. Exchangeable inside thread seat is used for NPS≿0" gate valve, random combine the material of surface of blow down part to meet the requirement of work status, prolong service life.
