Manual gate valve represent the most basic type of gate valve, operated by a handwheel or lever to raise or lower the gate. Their straightforward design and robust construction make them suitable for a wide range of applications, including:

• General industrial settings
• Water treatment plants
• Wastewater treatment facilities
• HVAC systems

Resilient Seat Gate Valves: Enhanced Sealing and Longevity

Resilient seat gate valves incorporate a resilient seat, typically made of rubber or synthetic materials, that provides a tight seal against the gate. This design reduces wear and tear, ensuring longer valve life and improved sealing performance. Resilient seat gate valves are commonly used in:

• Chemical processing
• Pharmaceutical manufacturing
• Food and beverage processing
• Mining and mineral processing

BS 5163 Resilient Seated Gate Valves: Adhering to Industry Standards

BS5163 resilient seated gate valve comply with the British Standard 5163, ensuring adherence to specific design, performance, and quality criteria. These valves feature a resilient seat and are widely used in:

• Water distribution systems
• Fire protection systems
• Marine applications
• Petrochemical industry

Comparative Analysis: Choosing the Right Gate Valve

When selecting the appropriate gate valve for a specific application, several factors must be considered:

Sealing Performance: Resilient seat gate valve and BS 5163 resilient seated gate valves offer superior sealing compared to manual gate valves, making them ideal for applications requiring tight shutoff.

Corrosion Resistance: Consider the valve body material and its compatibility with the fluid being handled to ensure corrosion resistance.

Pressure Rating: Ensure the gate valve’s pressure rating meets or exceeds the maximum system pressure.

Application Requirements: Evaluate factors such as temperature range, flow rate, actuation method, and industry standards to ensure the selected gate valve meets the specific application demands.
