Body: The NTVAL wedge gate valve body is made from cast steel, providing strength, durability, and low resistance to flow. It is designed to withstand demanding conditions and ensure long-lasting performance.

Yoke & Bonnet: The yoke and bonnet assemblies are crafted with the same high standards as the valve body. Larger gate valves feature a multi-piece bonnet design, which allows for easier assembly, maintenance, and overall valve stability.

Bonnet Gasket: The bonnet gasket creates a leakproof seal between the bonnet and the body, critical for preventing fluid leakage and maintaining valve integrity under pressure.

Bonnet Studs & Nuts: These secure the bonnet to the valve body, ensuring a tight, durable fit. Proper tightening of the studs and nuts is essential for maintaining the valve’s long-term sealing and performance.

Stem: Precision-machined for smooth operation, the stem is critical for controlling the valve. Its accurate alignment ensures effective valve function and contributes to the overall performance of the valve.

Stem Nut: Guides the stem for proper alignment, allowing for smooth opening and closing of the valve. It reduces wear and ensures reliable performance during operation.

Yoke Bushing: Secures the stem nut to the bonnet assembly and maintains the stem’s alignment, contributing to the valve’s stability and reliable operation.

Handwheel: Used for manually operating the valve, the handwheel allows the operator to open or close the valve. Its sturdy design ensures ease of use even with frequent operation.

Handwheel Nut: This secures the handwheel to the bonnet assembly, ensuring it stays firmly in place during operation. A properly secured handwheel nut prevents loosening.

Set Screw: Prevents the handwheel nut from loosening over time. This small but essential component helps maintain secure handwheel operation.

Gland: Compresses the packing to create a seal above the back seat, ensuring leak-free operation. Proper compression of the gland is vital for maintaining the valve’s sealing ability.

Gland Flange: Applies pressure to the gland, facilitating packing adjustments. This allows for precise control over the sealing pressure and smooth operation of the valve.

Gland Bolts & Nuts: Allow for easy adjustments to the packing compression. These components ensure the seal’s integrity over time and support reliable performance.

Gland Bolt Pin: Secures the gland bolts to the yoke and bonnet, preventing loosening during operation. It helps maintain consistent packing compression, which is critical for the valve’s performance.

Packing: Creates a seal above the back seat between the bonnet and the stem. Proper packing prevents leaks and ensures effective valve operation. Regular inspection and adjustment help extend the valve’s life.

Stuffing Box: Houses the packing and secures it within the valve, ensuring the seal remains tight. The stuffing box plays a critical role in preventing leaks and maintaining valve functionality.

Wedge: The one-piece flex wedge is machined to tight tolerances to provide reliable shutoff. This ensures proper valve closure and prevents leaks, making it essential for the valve’s sealing capability.

Back Seat Bushing: Engages with the stem head to provide a stable shutoff to the stuffing box, isolating the packing from flow exposure and improving the valve’s sealing performance.

Seat Rings: These are aligned and welded into the valve to create a stable shutoff. Precision ground after installation, the seat rings help ensure proper sealing when the valve is closed.

Spacer Ring: Assists the packing in creating a seal above the back seat. Positioned between the bonnet and stem, the spacer ring plays a key role in preventing leaks and maintaining valve performance.
