Integral flange globe valve

Forged steel self sealing globe valve refers to a valve in which the closing element (valve disc) moves along the centerline of the valve seat. According to the movement of the valve disc, the change in the valve seat opening is directly proportional to the stroke of the valve disc. Due to the relatively short opening or closing stroke of the valve stem and the highly reliable shut-off function of this type of valve.

Aluminum bronze integral forged flange gate valve

Bronze valves originally referred to copper-tin alloy valves. Later, copper alloys other than brass and cupronickel were called bronze, and the name of the bronze valve was often prefixed with the name of the main added element. The Aluminum bronze integral forged flange gate valve has high strength, good wear resistance and corrosion resistance. It is used to cast high-load gears, shaft sleeves, and marine propellers.

Hard sealed high platform ball valve

High platform ball valves are not only used for cutting off or connecting media, but also for regulating and controlling fluids. Compared with other valve types, ball valves have the advantage of low fluid resistance and are the ones with the smallest fluid resistance among all valve types. The product models of high platform ball valves are diverse, including Q41F, Q11F, Q14F, Q15F, etc. The nominal diameter range is from DN15 to DN800, the nominal pressure range is from 1.6Mpa to 16.0Mpa, and the applicable temperature range is wide, from -20 º C to+180 º C or even 550 º C. The valve body material includes stainless steel, 304, 316, 316L, etc., and the manufacturing standards comply with national standards such as GB, German DIN, American API, ANSI, etc. Applicable media include water, oil, steam, gas, corrosive liquids, etc.

Stainless steel hard sealed ball valve

What is a stainless steel hard seal ball valve？ Stainless steel hard sealed ball valve is an industrial equipment characterized by a metal to metal pairing of the sealing pair (i.e. the valve seat sealing surface and the ball sealing surface) of the ball valve. The structural form of this ball valve is divided into floating ball type and fixed ball type, and the connection forms include flange connection, welding connection, and threaded connection. The sealing characteristics of hard sealed ball valves are mainly the use of metal sealing pairs, which have the advantages of a wide temperature range, similar thermal expansion coefficients of various metals, and can achieve basic consistency as long as selected properly, which is conducive to coordinating temperature difference deformation. However, its disadvantage is that the material hardness is high, and the required specific pressure to achieve sealing is high. Even if pre tightening force is used to achieve sealing, the wear between the valve seat and the ball is also significant due to the high specific pressure of the seal. Moreover, due to the high friction coefficient of the metal sealing surface, the opening and closing torque of the ball valve is relatively large. Therefore, most hard sealed ball valves use elastic sealing pairs, which have reliable performance, strong elastic compensation ability, wide temperature range, and are suitable for both floating ball valves and fixed ball valves. ‌ The wide application of stainless steel hard sealed ball valves benefits from their unique advantages: compact structure, easy operation and maintenance, reliable sealing, small volume, can be made into large diameters, simple structure, and not easily eroded by media. These characteristics make stainless steel hard sealed ball valves perform well in controlling the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media, and therefore have been widely used in various industries。
