Large Transfer valve

Product catalog summary

Ordering Information: The document provides details on ordering a valve with a pneumatic actuator, specifically a double-acting type with a position indicator. It outlines different types of valve openings and configurations, including options with or without a bonnet flange and various opening sizes ranging from 50 × 500 mm to 150 × 1250 mm. Special sizes are available upon request.

Main Applications: The valves are suitable for FPD production systems up to generation 6 and are designed for high vacuum environments, such as vapor deposition systems for organic materials.

Features: The valve body is made of aluminum, utilizing MONOVAT sealing technology. It has a compact design with small mounting dimensions, specifically 95 mm for opening lengths up to 900 mm and 115 mm for lengths up to 1250 mm.

Technical Data: Key specifications include a leak rate of less than 1 · 10-9 mbar Is-1, a differential pressure on the gate of ≤ 1 bar, and a differential pressure at opening of ≤ 5 mbar. The valve can perform up to 1 million cycles until the first service, with a closing or opening time of ≤ 1.5 seconds for a 100 mm opening height. Temperature limits are set at ≤ 120 °C for the valve body and gate, and ≤ 60 °C for the actuator and position indicator.

Materials and Seals: The valve body and gate are made from EN AW-5083, while actuator shafts and differential pressure tabs are made from AISI 304. Seals are made from FKM (Viton®).

Mounting and Options: The actuator can be mounted in various positions (up, down, or lateral). Options include different sealing materials, bellows, grounding of the gate, and surface treatments like hard anodizing or nickel plating.
