The higher the pressure in the inner cavity, the better the sealing performance.2.Both ends can be connected by butt welding, which is suitable for different pipe connection requirements.3.The valve pressure bearing parts are made of high-quality heat-resistant alloy steel, which has good high-temperature performance, high pressure resistance, durability, safety and reliability.4.The sealing surface of the valve disc and valve seat is made of stellite cobalt-based hard alloy surfacing welding, which is wear-resistant, high temperature resistant, good scratch resistance and long service life.5.The valve disc rotates around the pin shaft outside the valve seat to reduce the violent impact when closing.6. The built-in pin structure reduces external leakage points and is more reliable in use. Scope Nominal size2"~24"(DN50~DN600)Nominal pressureClass 900~2500(PN160~PN420)StandardBS1868, API594,ASME B16.34Body materialCarbon steel, Stainless steel, Alloy steel, Duplex stainless steelEnd connectionRF, BW, RTJ Product ParametersCompany ProfileSUZHOU WALTER FLOW  is a genuine valve manufacturer. 7000-sqm factory100 employees5+ senior engineers30+ design patents2 million sets of valves delivered20 million USD annual revenueSince 1988, we have been expert in manufacturing a wide scope of industrial valves including:   Gate valvesGlobe valvesCheck valvesBall valvesButterfly valvesAPI valvesSteam valvesHigh pressure valvesHigh temperature valvesPower Plant valvesOur AdvantagesHeavy-duty valve expert with proven expertise in harsh environment;Stringent quality control and traceable reports to provide zero-defect products;Rugged and durable configuration according to API, ASME, BS, JIS, EN standards;All kinds of UG, PRO/E, Solidworks software simulations ensure the efficiency and robustness for tailored components;FAQ1.Q:Are you are a trading company or manufacturer?   A:We are a manufacturer with 7000-sqm factory and 100 employees.2.Q: Can you provide the assembly drawing for confirmation ?   A: Yes, we can give the relavant drawing within 24 hours.3.Q: Can you do non destructive test for valve components ?   A: Yes, we can perform radiographic testing, penetration testing, ultrasonic testing, magnetic particle testing, etc4.Q: How can I vist you when I am in China?   A: We are near the Wenzhou Airport.
