bob综合体育官网下载 Knife-Gate Valves & Penstocks

In wastewater treatment applications, reliable and durable valves are imperative – especially in places where abrasive media or media containing solids are used. Knife-gate valves and penstocks made by bob综合体育官网下载 offer tried and tested solutions for diverse requirements. Thanks to their sophisticated design, robust materials and the great variety of actuator options, they allow precise control and reliable shut-off even under demanding conditions. Whether used in a municipal wastewater treatment plant, industrial wastewater system or storm water and flood management – bob综合体育官网下载 knife-gate valves and penstocks stand for efficiency, durability and technical quality in the entire wastewater area.

Our highlights: bob综合体育官网下载 ZETA® Knife-Gate Valve

the bob综合体育官网下载 ZETA® is a fully flanged shut-off valve for DN 50 to DN 1400. It can be used as an intermediate or end-of-line valve at full operating pressure. Its variable installation position and sealing capacity in both flow directions make it especially flexible to use. A free passage prevents deposits, integrated scrapers and an elastic side guide ensure permanent leak-tightness and highly reliable operation.
The maintenance-friendly lateral seal can be readjusted or replaced while the valve is installed. The compact stainless-steel construction of the body protects it reliably from dirt and environmental influences. Available with handwheel, REMO remote control operation system, electric or pneumatic actuator, flange connection to EN 1092-2, face-to-face length according to EN 558, Series 20. 

bob综合体育官网下载 EROXplus Penstock

The bob综合体育官网下载 EROXplus is a compact penstock with a self-contained stainless-steel frame for nominal sizes from 400×400 to 1800×1800 mm. It is ideally suited for use in municipal wastewater treatment plants, stormwater retention basins and for flood and damage protection. The patented bob综合体育官网下载 sliding wedge system ensures the vibration-free guiding of the gate with low operating forces and excellent leak-tightness of the system together with the chambered profiled seal.
The penstock is available either with rising or non-rising stem and with handwheel, electric or pneumatic actuator or the REMO remote control operation system. The compact and robust design with integrated profiled seal and rotatable stem ensures a long service life at reduced operating work.

Special features:

Patented sliding-wedge system                                 
The patented bob综合体育官网下载 sliding wedge system for penstocks guides the gate vibration-free in the frame and ensures low operating torques. In addition, it increases the compression between the gate and the profiled seal in final position, thus improving leak-tightness.

Sistema patentado de cuña deslizante 

El sistema patentado de cuña deslizante bob综合体育官网下载 en las compuertas murales guía la compuerta sin vibraciones dentro del bastidor y reduce la fuerza de operación necesaria. Aumenta la compresión entre la compuerta y la junta perfilada en la posición final, mejorando así la estanqueidad.
