Product catalog summary
Overview
This document provides technical details about the Rotary Valve Type EZS, a versatile device used for metering, discharging, or feeding powdery and granular products. It is applicable in various industries such as chemical, pharmaceutical, food, and plastics.

Specifications
The rotary valve is available in construction sizes DN200 and DN250 and is designed for continuous operation. It features a cast housing with round inlets and outlets, an 8-compartment rotor, and is made from materials like grey cast iron and stainless steel. External antifriction bearings and various sealing options are available.

Applications
The valve can be used as a shut-off device after separators, a feeding device into pneumatic conveying units, and a metering device for drawing off products from silos and containers. It is also suitable for feeding downstream machines.

Advantages
The design includes diagonal chambers for gentler conveying, reducing dust content and noise levels by 2-3 dB(A). The optimized shear edge reduces engine power requirements. Optional bore holes allow for leakage air discharge, and the bucket wheel can be easily cleaned due to its draw-out execution.

Protective System
The rotary valve is flashback resistant and suitable for use in zones 0/1/2 and 20/21/22 inside, and zones 1/2 and 21/22 outside. It meets ATEX conformity according to regulation 94/9 EC, with a minimum ignition energy of >3 mJ and an ignition temperature of >360°C, suitable for dust explosion class ST1.

Additional Products
The document also mentions other rotary valves in the manufacturing program, including Metering Rotary Valve S-LK, Pneumatic Rotary Valve D, and Rotary Valve for Granulate NZS.
