Pressure Seal Gate Valve Manufacturers in USA

SVR Global is a industry-leading pressure seal gate valve manufacturers in USA, supplying high-pressure, high-temperature, and heavy-duty valves designed for the most demanding industrial applications. Engineered with precision using premium materials such as carbon steel, alloy steel, stainless steel, chrome-moly, and forged steel, our pressure seal gate valves are built to withstand extreme service conditions found in power plants, refineries, petrochemical units, and high-pressure steam systems.

Recognized for reliability, long service life, and exceptional sealing integrity, SVR Global pressure seal gate valves deliver outstanding performance across critical American industries that prioritize safety and operational efficiency.

What is a Pressure Seal Gate Valve ?

1. Engineered for High Pressure & High Temperature

Pressure seal gate valves are ideal for:

• Power plants


• High-pressure steam lines


• Thermal and nuclear systems


• Petrochemical reactors


• High-temperature boiler operations

The pressure seal design ensures the bonnet gasket tightens as internal pressure increases, providing a superior seal and zero leakage.

2. Superior Pressure Seal Bonnet Design

Our pressure seal valves include:

• Self-energizing bonnet seal


• Automatic tightening under pressure


• Reduced body-bonnet bolting


• Lower leakage probability


• Longer valve life

Perfect for extreme-pressure environments commonly found in US power and refinery plants.

3. Manufactured With Premium Materials

SVR Global pressure seal gate valves are available in:

• ASTM A216 WCB / WCC


• ASTM A217 WC6 / WC9 / C5 / C12


• Alloy Steel (F11, F22)


• Stainless Steel (SS304 / SS316 / SS316L)


• High-temperature chrome-moly steels

Ensuring stability, corrosion resistance, and outstanding high-temperature performance.

4. Designed to International Standards

Our valves comply with:

• API 600 / API 602 / API 6D


• ASME B16.34


• BS / DIN / ASTM specifications


• Pressure Classes: 600, 900, 1500, 2500, 4500


• End Connections: Butt Weld, Flanged, RTJ

Fully tested for pressure, leakage, and material integrity.

Types of Pressure Seal Gate Valves -

1. Pressure Seal Gate Valve (Standard Design)

• Ideal for high-pressure steam systems


• Stable sealing with rising internal pressure

2. Pressure Seal Flexible Wedge Gate Valve

• Handles temperature fluctuations


• Reduces seat stress and improves sealing

3. Pressure Seal Solid Wedge Gate Valve

• Strong and rigid construction


• Best for consistent operating temperatures

4. Pressure Seal Parallel Slide Gate Valve (On Request)

• Excellent for high-temperature steam


• Zero leakage and low seat wear

5. Pressure Seal Forged Gate Valve

• Stronger and more durable


• Ideal for severe industrial environments

Key Parts of Pressure Seal Gate Valves

• Pressure seal bonnet


• Body (carbon steel, alloy steel, stainless steel)


• Gate / wedge (solid or flexible)


• Stem (anti-blowout design)


• Seat rings (hardened for longevity)


• Bonnet gasket / graphite packing


• Handwheel or gear operator


• End connections: BW / Flanged / RTJ

All components are built for long-lasting, high-integrity service.

Advantages of Pressure Seal Gate Valves

• Excellent performance in extreme pressure & temperature


• Automatic bonnet sealing improves with pressure


• Reduced bolt load and lower maintenance


• Long service life in severe high-pressure systems


• Superior sealing reliability


• Low torque and smooth operation


• Resistant to thermal stress and deformation


• Ideal for steam, gas, and critical service media

Industries using Pressure Seal Gate Valves
