VARIVENT®
This document provides a comprehensive analysis of various valve types, including modulating control valves, safety valves, overflow valves, vacuum valves, and sampling valves. It details their specifications, design features, and technical data, emphasizing their applications in industrial processes.
These valves are essential for pressure control, flow regulation, and liquid mixing. They feature high-accuracy positioners and are housed in a cleanable VARIVENT® housing. The design includes linear or equal percentage control cones and exchangeable valve seats for adaptability.
Materials include stainless steel for housing and product contact parts, with seals in EPDM, FPM, FFPM, or MVQ. The surface finish is matt outside and Ra ≤ 0.8 µm inside, with a maximum control air pressure of 6 bar.
Additional functions include shut-off capabilities with V-ring seat seals and various connection fittings. Positioners, both mechanical (Type 824) and electronic (Type 827), enhance control accuracy.
Safety valves are spring-loaded for specific applications, while overflow valves manage system pressure. Actuator selection is crucial for performance.
Vacuum valves are designed for specific pressure conditions, and sampling valves facilitate sample extraction. Accessories enhance functionality.
These valves are designed for industries like food and beverages, ensuring compliance with international standards. VARIVENT® valves operate within 0.2 to 16 bar and temperatures from -40 to +135°C. HyCom valves offer a cost-effective alternative with a pressure range of 0.5-10 bar.
Both valve types comply with the EU Pressure Equipment Directive and are TÜV type-tested. VARIVENT® valves offer manual and pneumatic lifting devices.
High-quality construction, temperature insensitivity, and CIP-capable design ensure worldwide approvals and compliance.
Designed for hygienic and performance requirements in food, brewery, and beverage industries, ensuring reliable overpressure protection.
VARIVENT® valves have a maximum set pressure of 16 bar, approved by VdTÜV and ASME. HyCom valves are TÜV-approved for non-toxic applications.
Details include materials like 1.4404/316L for product-wetted parts and adjustable springs for different valve types.
Tables show discharge capacities for air, water, and steam, crucial for valve performance understanding.
HyCom Safety Valves, VARIVENT® Overflow Valves, D-Force Valves, and Vacuum Valves are detailed for specific applications.
Emphasizes correct valve sizing and benefits like reduced costs with VARIVENT® D-Force Q valve.
Suggests appropriate actuator and spring pack use and highlights hydraulic calculations for vacuum valves.
Designed for valve seat cleaning during tank cleaning, requiring at least 6 bar control air pressure.
Proximity switch detects valve position, operating at 10 – 30 VDC.
Combines pneumatic lifting actuator and proximity switch functions.
Recommended for vacuum valves in freezing conditions, operating at 24 VAC.
Provides dimensions for sampling valves according to various standards.
Ensures safe discharge of sample volumes, with specific nozzles for CO2-containing liquids.
