ZCLQ Pneumatic Thin Film Cut off Valve

Product Features
The emergency cutting and spray coating process of the film mechanism has an exquisite appearance
Multiple structures widely used, special sealing action sensitive

Product Overview
The 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, temperature or liquid level. Widely used in automatic and remote control systems for production processes in various industrial sectors such as petroleum, chemical, metallurgical, power, light industry, textile, etc.
This series of products comes in two types: film type and piston type. There are three types of valve body structures: single seat, sleeve, and double seat (two position three-way). The sealing forms include packing sealing and corrugated pipe sealing. The nominal pressure rating of the product is PN10, 16, 40, and 64, and the nominal diameter range is 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 connected to the regulating mechanism with three columns, 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 rated flow coefficient by 30%.
·There are two types of sealing parts for valve internals: tight type (welded hard alloy) and soft seal (soft material), which have excellent sealing performance when closed.
·The 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.
