ZMQM Pneumatic Thin Film Sleeve Cut off Valve
Instructions for Use The ZMQM pneumatic thin film sleeve cut-off valve adopts a top guide structure and is equipped with a multi spring actuator. It has the advantages of compact structure, light weight, sensitive action, S-shaped fluid channel, low pressure drop loss, large valve capacity, and easy disassembly and assembly. The cut-off valve receives signals from the regulating instrument to cut off, open, or change the flow direction of the medium, achieving automatic control of process parameters such as pressure, flow rate, and liquid level. Widely used in production process automatic control and transportation control systems in various industrial sectors such as petroleum, chemical, metallurgical, power, light industry, textile, etc. This series of products has four nominal pressure levels: PN10, 16, 40, and 46, with a nominal diameter range of DN20-200mm. The applicable fluid temperature ranges from -60 to 450 ℃. The leakage level is IV or VI. The traffic characteristic is fast opening. Product Features ◇The cut-off valve adopts a multi spring actuator and a regulating mechanism connected by three vertical poles, which can reduce the overall height by about 30% and the weight by about 30%. ◇The valve body is designed according to the principles of fluid mechanics as a low flow resistance channel with equal cross-section, increasing the number of rated flow systems by 30%. ◇There are two types of sealing parts for valve internals: tight type and soft type. The tight type is made of hard alloy welding, while the soft type is made of high-quality materials, with excellent sealing performance when closing. ◇ Balanced valve internals increase the allowable pressure difference of the shut-off valve. ◇The bellows sealing type forms a complete seal for the moving valve stem, blocking the possibility of medium leakage. ◇Piston type actuator, with high operating force and large pressure difference.
