Shut-off valve GLO Fig. 215 DN100 PN16, gray cast iron EN-GJL-250, construction: 92, stem-to-bonnet connection – detachable – threaded, stem – brass, control mushroom and body ring – bronze, with opening indicator 215A100C92

The shut-off valve GLO Fig. 215 DN100 PN16 is a robust solution for isolating medium flow in various installations. Manufactured from gray cast iron EN-GJL-250, it ensures durability and corrosion resistance. The design features a detachable stem-to-mushroom connection (threaded) for simplified servicing and replacement of internal components.

Construction and Application

This flanged valve with nominal diameter DN100 and pressure class PN16 is designed for use with hot, cold, cooling water, and steam. It performs reliably in industrial processes, heating systems, and power generation applications. Thanks to high tightness (Class A per EN 12266-1), it minimizes leakage risk and ensures safe operation. The opening indicator enables quick visual verification of valve position, which is especially critical in automated and remotely controlled systems.

The valve complies with the Pressure Equipment Directive 97/23/EC and carries CE marking for diameters from DN32, confirming conformity with European safety standards. Flanges are machined according to EN 1092-2 for body material group A, and face-to-face dimensions conform to Series 1 per EN 558-1 — guaranteeing compatibility with existing infrastructure.

Materials and Design Features

Key to the valve’s reliability is the use of a brass stem, bronze regulating mushroom, and bronze body ring. These materials offer high resistance to corrosion and wear, significantly extending service life. The brass stem ensures smooth valve operation, while the bronze regulating mushroom enables precise flow control — available in throttling (regulating) configuration.

The valve is compatible with popular calculation software such as Instal-therm, Instal-san, Audytor C.O. 3.8, and Audytor H2O 1.5, facilitating professional design and system optimization.
