Rising Stem Gate Valve Rubber Seat Ductile Iron Resilient Seated Gate Valve 2’’-48’’

Product Description

The opening and closing component of the gate valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces, and the most commonly used mode is that the two sealing surfaces of the gate valve form a wedge shape. The wedge angle varies depending on the valve parameters, usually 50, and is 2 ° 52 'when the medium temperature is not high

Manual Gate Valve With WRAS Approved Epoxy Coating features and advantages:

1. ANSI rising stem gate valve

• The stem rises out of the bonnet as the valve opens, enabling linear upward movement of the gate to open the flow way.
• The threaded stem connects to the gate for precise control of gate position by rotating the stem.
• Complies with ANSI standards for easy installation and maintenance.

2. Rubber seat

• The seat is made of resilient rubber material for tight shutoff and leak prevention.
• Rubber is gentle on the gate resulting in less wear and longer service life.
• Good sealing ability is maintained even after prolonged use.

3. Ductile iron valve body

• High strength ductile iron body resists corrosion and abrasion.
• Can handle higher water pressure and temperature.
• Provides reliable sealing and long service life.

4. Resilient seated gate technology

• Bidirectional sealing of the gate against the resilient rubber seats.
• Self-aligning rubber seats provide positive shutoff when fully closed.
• Gate wear does not affect sealing performance.

In summary, this valve offers wide applicability, high quality-to-cost ratio, making it one of the most commonly used valve products for industrial and domestic piping systems.

FAQ

What is an ANSI rising stem gate valve?

• ANSI rising stem gate valves are linear motion valves where the stem rises out of the valve bonnet as the valve is opened. They have a non-rotating stem that is threaded into the gate. As the handwheel on the stem is turned, the gate moves up or down to regulate flow.

What are the typical components of an ANSI gate valve?

• Bonnet: Covers the stem and gate assembly
• Stem: Connects the gate to the handwheel, rises as valve opens
• Gate: Flow control element that seals against the seats
• Seat: Sealing surfaces for the gate, usually replaceable
• Body: Main pressure carrying part of the valve

What is a rubber seated gate valve?

• A rubber seated gate valve uses resilient rubber material for the seats instead of metal seats. The rubber provides a tight seal against the gate but is softer than metal so it is less likely to damage the gate.

What is a ductile iron gate valve?

• Ductile iron is a type of cast iron that has additives to increase strength and flexibility. Ductile iron gate valves are more durable than standard cast iron valves. They resist impact better and can handle more pressure.

What are the benefits of rubber seats?

• Rubber seats provide tight shutoff while being gentle on the gate. This extends the life of the gate and seats compared to metal seats. Rubber seats are also less prone to leakage than metal seats after extended use.

What are the main differences between metal seated and rubber seated gate valves?

• Metal seats provide high strength and temperature resistance but are more prone to leakage over time. Rubber seats offer tighter shutoff and bidirectional sealing capability but have lower pressure and temperature limits.

How do you inspect and maintain gate valve seats?

• Periodically inspect the seats through the end ports of the valve. Look for wear, pits, grooves, and embedded particles. Maintain by cleaning debris from seats and gate. Lubricate stems. If seats are worn, have a qualified technician replace them.
