Jerguson® Safety Ballcheck Valves help protect glass level gage assemblies in demanding industrial applications. In addition to isolation, these valves provide automatic shut-off for glass level gage products during severe glass or gasket failure.
Jerguson Safety Ballcheck Valves are available with integral, union, bolted bonnet, OS&Y, and jacketed valve arrangements. As a result, users can match the valve style to the pressure rating, connection requirements, gage design, maintenance needs, and emissions requirements of the application.
Westech Industrial offers the following Jerguson Safety Ballcheck Valve series Canada-wide:
- Jerguson 360 Series: Innovative core design with an internal ballcheck located within a metal seated valve.
- Jerguson Series 70BL™ and Series 70XL™: API 624 certified low-emission, 600 lb. ANSI rated valves with bolted bonnet OS&Y construction, steel bodies, stainless steel trim, and a wide choice of features and connections.
- Jerguson 60LE Series: Low-emission certified to API 624 to support EPA compliance requirements.
- Jerguson Series 60™: Union bonnet valves with steel bodies, stainless steel trim, and a wide choice of features and connections.
- Jerguson Series 140™: Integral bonnet valves with steel bodies, stainless steel trim, and a wide choice of connections.
- Jerguson Series 70™: 900 lb. ANSI rated valves with bolted bonnets and OS&Y construction.
- Jerguson Series 86™: High-pressure valves with bolted bonnet and OS&Y construction.
- Jerguson Series 90™: Jacketed valves for heated or cooled gages, or other services requiring small jacketed angle valves.
Depending on the selected series and configuration, Jerguson Safety Ballcheck Valves support application pressures up to 10,000 PSI. This makes the product family suitable for a wide range of level indication applications, from standard flat glass gages to high-pressure or temperature-controlled services.
Westech Industrial can help customers select the right Jerguson safety ballcheck valve for their gage assembly, process conditions, and site requirements. Our team can also support service needs, complete level indication packages, and custom fabrication requirements for integrated industrial solutions.

Description
Automatic Shut-Off for Glass Level Gages
Jerguson safety ballcheck valves provide more than basic isolation. They add an internal ballcheck upstream from the seat. During a severe glass or gasket failure, the ballcheck helps shut off process flow to the gage. This feature supports safer operation and helps reduce the impact of unexpected gage damage.
Selected Jerguson Safety Ballcheck Valve series can also be configured without a ballcheck when the application requires it. However, safety ballcheck valves remain the preferred choice where automatic shut-off matters.
360 Series Commissioning Protection
The Jerguson 360 Series improves safety during commissioning. Its core design places an internal ballcheck inside a metal seated valve. It also uses a bypass mode that helps reduce false level readings when liquid already exists in the vessel.
Operators can use the visible quarter-turn handle to confirm valve status. The colour indicator ring shows run mode, bypass mode, or closed position. In addition, the standard lock-out/tag-out capability helps support controlled maintenance procedures.
The 360 Series also suits emissions-focused applications. It carries low-emission certification to API 641 and ISO 15848-1. It also meets API Class V shut-off requirements.
Low-Emission Safety Ballcheck Valve Options
Several Jerguson safety ballcheck valves support low-emission requirements. The 60LE Series carries API 624 certification and keeps stem threads outside the process fluid. This design helps reduce thread corrosion and supports smoother handwheel operation.
The Series 70BL and Series 70XL platform also supports API 624 low-emission requirements. These 600# ASME rated valves use bolted bonnet OS&Y construction, steel bodies, stainless steel trim, and multiple connection options.
Series 70 valves also provide API 624 low-emission performance in a 900# ANSI rated design. Therefore, users can select a higher-pressure bolted bonnet option when the application requires it.
Bonnet Styles for Pressure and Maintenance Needs
The Jerguson safety ballcheck valves lineup covers several bonnet arrangements. Series 140 uses an integral bonnet design for economical, dependable service. Series 60 and 60LE use union bonnet construction for flexible installation and maintenance.
Series 70, Series 70BL/70XL, and Series 86HO use bolted bonnet construction with OS&Y features. This design keeps the stem threads away from the valve body. It also prevents direct contact between threads and process fluids.
For high-pressure applications, Series 86HO supports pressures up to 10,000 PSI at 400°F when configured with Viton® O-rings. It also pairs with Jerguson high-pressure flat glass gages.
Serviceable Seats, Unions, and Connection Choices
Many Jerguson safety ballcheck valves include regrindable, renewable seats. This feature can help extend service life and simplify maintenance. Union process or gage connections also improve access and alignment.
Selected union gage configurations allow the gage to rotate for improved visibility. They also allow gage removal without removing the valves or draining the vessel. Additionally, offset body options allow gage cleaning by removing the vent or drain plug.
Heated and Cooled Gage Service
Series 90 safety ballcheck valves support heated or cooled gage applications. Their jacketed design allows heating or cooling media to circulate around the valve. This makes Series 90 suitable for reflex or transparent flat glass gages that need thermal control.
