Isolation Valves – Reliability and Durability in Every System

This cast iron isolation valve, ZGLO, model 215, with nominal diameter DN32 and pressure class PN16, is a robust solution for diverse installations. Manufactured from high-quality gray cast iron (EN-GJL-250), it ensures long-term, trouble-free operation. This valve is particularly valued for its versatility and resistance to harsh operating conditions.

The valve features a design in which the stem-to-disc connection is detachable, achieved via a screw. The stem, regulating disc, and body ring are made of stainless steel, guaranteeing corrosion resistance and ensuring the longevity of components critical to sealing. The absence of an opening indicator simplifies the design and minimizes the risk of failure.

Application and Design Features

The ZGLO valve is widely used in hot and cold water, cooling systems, as well as in steam systems and industrial technologies, district heating, and power generation. It complies with the Pressure Equipment Directive 97/23/EC and carries the CE marking for diameters from DN32, confirming compliance with European safety standards. The installation length conforms to EN 558-1 Series 1. Flanges are machined according to EN 1092-2 for body material A.

High sealing performance (Class A per EN 12266-1), along with testing and inspections conducted in accordance with EN 12266-1, guarantee reliable operation and minimize leakage risk. This valve is suitable for use with aqueous media but is not intended for gases. It may also be used in steam systems.
