Rugged Flow Control, Delivered: Fox Global Sends 25 x Glen Shouldered Butterfly Valves to Western Sydney Tunnelling Project

In the high-pressure, high-stakes world of tunnelling infrastructure, flow control equipment must do more than work—it must endure. That’s why a major Western Sydney tunnelling contractor turned to Fox Global for fast, site-ready supply of 25 x Glen Shouldered Butterfly Valves.

These valves, ranging in size from 2″ (50NB) to 8″ (200NB), are engineered to thrive in extreme conditions, with NBR-lined and 316 stainless steel variants, multi-stop handle controls, and impact-resistant epoxy coatings.

This delivery not only highlights the rugged performance of Glen valves—it reflects the values we bring to every order: speed, service, and solutions.

1. Project Snapshot: Western Sydney Tunnelling

Western Sydney is undergoing unprecedented infrastructure expansion. With major tunnelling works underway to support transport, utilities, and growth corridors, civil contractors require trusted supply partners that can deliver critical components on time and to spec.

In this case, the contractor needed 25 Glen Shouldered Butterfly Valves, urgently, in a mix of sizes to control water and fluid movement within the tunnel network during early-phase works.

The valves were required for:

Dewatering systems
Line isolation
Flow throttling
Emergency shutoff functions

Given the tunnel’s confined spaces, pressure variation, and demand for low-maintenance gear, butterfly valves with a compact profile and rugged build were ideal.

2. The Valves: Glen Shouldered Butterfly Series

We supplied a batch of 25 Glen Shouldered Butterfly Valves, ranging in nominal bore from 50NB to 200NB, each manufactured to international quality and pressure standards.

Here’s why this product line excels in demanding projects like tunnelling, mining, and water infrastructure:

Key Features:

✅ Size Range: 50NB (2″) to 200NB (8″)
✅ Max Pressure Rating: Up to 25 Bar (362.5 psi)
✅ Temperature Range: -20°C to +80°C
✅ Body Coating: Impact-resistant FBE coating (RAL 5005 gloss)
✅ Seal Options: NBR rubber lined or 316 stainless steel seat/trim
✅ Handle Variants: 90° multi-stop handle or handwheel-operated
✅ Manufacturing Standards: Built in ISO 9001:2015 accredited facilities

3. Why Glen Valves Are Tunnel-Ready

Tunnel environments present unique challenges:

Confined space
High humidity and water ingress
Difficult access for maintenance
Constant vibration or mechanical shock
Corrosive and abrasive suspended solids

The Glen Shouldered Butterfly Valve series is engineered to overcome these challenges with:

🛠️ Rugged Design

The ductile iron body and NBR lining offer high mechanical strength and chemical resistance.
Impact-resistant epoxy coating resists abrasion and mechanical damage.

💧 Leak-Free Performance

The rubber-seated disc ensures bubble-tight sealing, even under high pressure.
Excellent for flow isolation, drainage, or throttling in water pipelines.

🔧 Easy Installation & Operation

No lubrication required
Quick-fit assembly with grooved or flanged pipelines
Multi-stop handles allow for fine control during flow regulation.

🧰 Minimal Maintenance

Designed for long cycles without lubrication or seal replacement.
Easily operable even after long static periods—ideal for emergency isolation.
