Valves play a critical role in controlling fluid flow, and gland packing ensures they remain leak-proof even under extreme pressure and temperature. Among the most trusted sealing materials are Graphite, PTFE (Teflon), and Grafoil – each with specific advantages tailored for different valve types and industrial conditions.

At Udhhyog, Delhi’s top gland packing supplier and valve manufacturer, we provide high-performance sealing solutions for gate, globe, and control valves, serving industries like steam, chemical, water treatment, and power generation.

This article breaks down the properties and applications of graphite, PTFE, and Grafoil gland packing and provides specifications for their ideal use in valves.

What is Gland Packing?

Gland packing is a sealing material inserted around the valve stem inside a chamber known as the stuffing box. It prevents leakage by forming a tight seal when compressed using a gland follower and gland flange.

Gland packing is one of the most critical components used in valves to ensure sealing between the valve stem and the bonnet. Whether in steam, gas, or chemical applications, proper gland packing prevents leakage, enhances valve life, and ensures safety and efficiency in pipeline systems.

As a reputed valve and gland packing supplier in Delhi, Udhhyog offers a wide variety of gland valve types, packing materials, and solutions tailored to industrial needs.

This article provides a complete overview of what gland packing is, the types of materials used, application-specific specifications, and valve compatibility.

What is a Valve Used For?

Valves are mechanical devices used to control, regulate, or shut off flow in piping systems. They are used in:

Oil & Gas Pipelines

Steam Systems

Water Treatment Plants

Chemical Processing

HVAC Systems

Valves like gate, globe, ball, and control valves rely heavily on gland packing to ensure leak-proof stem operation.

What is Gland Packing in Valves?

Gland packing is a sealing material compressed between the valve stem and bonnet through a gland follower and gland flange. It prevents media leakage along the stem, especially under pressure and temperature.

Common in:

Gate Valves

Globe Valves

Ball Valves

Control Valves

Steam Valves

Gland Valve Anatomy

Key components:

Gland – The upper compression ring

Gland Flange – Holds the gland in place

Packing Rings – Made of PTFE, graphite, asbestos-free yarns, etc.

Stuffing Box – Chamber where packing is placed

Gland Follower – Compresses packing uniformly

Types of Gland Packing Materials

🔹 1. Graphite Gland Packing

Temperature resistance: up to 550°C

Excellent for steam and high-temperature valves

Product Example: Grafoil gland packing

🔹 2. PTFE Gland Packing

Chemically inert and non-stick

For acidic and alkaline media

Ideal in control valves and chemical service

🔹 3. Carbon Fiber Packing

High strength and thermal conductivity

Used in high-speed and abrasive services

🔹 4. Spitmaan Gland Packing

Brand known for steam valve sealing

Available in graphite and PTFE variants

🔹 5. Asbestos-Free Synthetic Packing

Complies with modern safety standards

Good for general water and fluid services

Gland Packing Specifications

✅ Gland Packing Sizes

Standard cross-section: 3mm to 25mm

Common sizes: 10mm gland packing, 12mm, 16mm

✅ Temperature Resistance

Graphite: Up to 550°C

PTFE: Up to 260°C

Carbon: Up to 650°C (with inhibitors)

✅ Pressure Handling

Ranges from 10 bar to 250 bar, depending on material and construction

Gland Packing by Valve Type

🔸 Gate Valve Gland Packing

Requires tight sealing during full open/close cycles

Use graphite or carbon-based materials

🔸 Globe Valve Gland Packing

For high-throttle operation, needs durable and flexible packing

Graphite/PTFE hybrids recommended

🔸 Ball Valve Gland Packing

Found in stem sealing areas

PTFE preferred for low-torque rotation

🔸 Control Valve Gland Packing

Needs flexible, low-friction, chemically inert materials

PTFE or expanded graphite

🔸 Steam Valve Gland Packing

Must withstand high temperature and thermal cycling

Use graphite or Spitmaan graphite gland packing

Gland Packing for Steam Valves

Steam valves operate under extreme temperatures and pressure, and leakage can cause energy loss and hazards. Preferred materials include:

Flexible graphite

Carbon-impregnated PTFE

High-temperature Spitmaan yarns

Installation requires:

Proper ring stacking

Uniform compression

Avoiding over-tightening (can damage stem)
