Product Description

Pneumatic PTFE-Lined regulating ball valve,Corrugated pipe PTFE regulating valve,Teflon-lined balanced regulating stainless steel valve
(ZPL500 series)

The ZPL500 series of Fluorine -lined control valves are coated with a layer of Polytetrafluoroethylene plastic on the surface of the valve body and valve core that comes into contact with the fluid, completely cutting off the corrosive medium from contact with metal and effectively blocking the corrosive medium from corroding all metal materials. It has good sealing performance, sensitive action, precise flow characteristic, and is widely used in strong corrosive media such as acids, alkalis, salts and gaseous and liquid media that are easy to volatilize and penetrate.

ZPL500 series Fluorine-lined regulating valve Classification:

1. ZPL510F Airtight Fluorine-lined regulating valve 
2. ZPL510WF Corrugated pipe + Airtight Fluorine-lined regulating valve
3. ZPL520F Fluorine-lined balanced regulating valve

ZPL5-10WF Fluorine-lined control valve (Corrugated pipe and packing seal) has the performance of ZPL5OF valve stem seal structure, and adds PTFE Corrugated pipe seal and V-shaped Fluorine packing as two combination seals. This eliminates any leakage of the medium from the valve stem. It can achieve multiple sealing protection to prevent medium leakage and provide better sealing guarantee for demanding media (chlorine, liquid chlorine, etc., which are highly toxic and strongly corrosive).

Installation Notes
1.After carefully inspecting the valve (position number, type, diameter, pressure, material, etc.), prior to installation, ensure that it complies with the required specifications and that the flow direction indication on the housing aligns with the fluid flow direction in the pipeline.
2. The valves should be installed vertically on horizontal pipelines with the actuator positioned above, and tilting installation should be avoided. Vertical installation is strictly prohibited for valves with a diameter of 65mm or above (including 65mm).
3.If the metal flange or valve connected to the valve is used, a fluorine plastic sealing gasket must be used to prevent the valve sealing surface from being damaged and leaking prematurely.
4, The installation of a bypass can guarantee uninterrupted production in the event of product maintenance or failure.
5, The product is meticulously designed and manufactured in strict accordance with the specified parameters outlined in the technical specifications. In case of any changes to the usage parameters, please promptly contact our company (special requirements should be communicated prior to placing an order).
6,The product has undergone thorough inspection and calibration prior to shipment. If feasible, it is recommended to perform an additional examination of the seal and external leakage before installation.
7,The product's accessories have been carefully adjusted to the optimal position prior to leaving the factory, therefore it is advised not to make any random adjustments.
8,The pipeline must undergo blowing and testing both before and after installation. In this particular scenario, it is essential for the valve to be fully open.
