Overview
The Nil-Cor 310 ST-T-H-A is a 2″ fiberglass composite ball valve engineered for industrial fluid control in corrosive environments. With an ANSI 150 rating and 150 psi maximum pressure, this valve delivers reliable performance and durability. The one-piece body design eliminates leak paths inherent in body joints, making it ideal for pressurized piping systems handling aggressive chemicals.
Key Features
- Compression-molded fiberglass and epoxy novolac vinyl ester resin body for lightweight, corrosion-resistant construction
- Hastelloy-C gland with integral locking plate and Hastelloy-C stem with molded graphite fiber/vinyl ester composite on wetted surfaces
- Blow-out proof stem and self-relieving seat design eliminating need for ball cavity relief holes
- PTFE V-Ring packing, PTFE-coated FKM elastomer O-rings, and self-relieving virgin PTFE seats
- Unique color coding for easy field identification
Technical Specifications
This 2″ valve is rated ANSI 150 with pressure rating of 250 PSIG at -50°F and 250°F (19 BARG at -46°C and 121°C). The valve features a full-port design with low pressure loss and minimal actuation torque requirements.
Typical Applications
Nil-Cor ball valves are used for corrosive chemical service in construction of pressurized piping systems. The composite construction makes this valve suitable for handling bleach, caustics, acids, and other aggressive chemicals where metal valves would corrode. Common applications include chemical processing plants, water treatment facilities, industrial water recirculation systems, and specialized industrial piping networks.
Compatibility & Replacements
Compatible With
- ANSI 150 flanged connections (2″ bore)

Replaces / Drop-In Replacement For
The Nil-Cor 310 ST-T-H-A is the specific 2″ ANSI 150 configuration. Related 310 Series valves in different sizes (e.g., 3″ 310-ST-T-H-S) share the same internal design but require proper flange matching. Verify size and flange class with your system integrator before ordering.
Works With
- Manual lever actuation (hand operation)
- Pneumatic/hydraulic actuator kits (custom orders available)
- Dresser coupling connections for end-port designs
- Industrial process control systems requiring corrosion-resistant isolation
