Globe valve MN-723

hydraulically-operatedfor controlpilot

Overview
Hydraulically pilot-operated control valve with two independent functions: pressure reducing and pressure sustaining. It sustains a minimum preset upstream pressure regardless of flow variations or downstream pressure changes, and prevents downstream pressure from exceeding a maximum preset regardless of flow fluctuations or excessive upstream pressure. The 700 Sigma Series features a hydrodynamic, obstacle-free flow path and is designed for effective modulation in high differential pressure systems. Built for demanding environments to minimise cavitation and noise, suitable for waterworks, mining and heavy industrial applications.

Key features

• Tamper‑resistant design
• Excellent anti‑cavitation performance
• Wide flow range for precise modulation
• High pressure stability and accuracy
• Drip‑tight sealing
• Hydrodynamic, obstacle‑free flow path
• Optional V‑Port throttling plug for improved low‑flow stability

Design & actuator

• Double‑chamber unitized actuator, removable as a single integral unit
• Protected diaphragm
• Rapid response to sudden system condition changes
• Simplified maintenance: actuator and seat assembly are in‑line serviceable

Applications

• Waterworks and municipal supply
• Mining and heavy industry
• High differential pressure systems requiring combined reducing and sustaining functions
