Rubber Lined Ball Valve

Product Overview

At Vcore Valve we manufacture and supply rubber lined ball valves designed for the harshest process conditions. In many industries our customers handle corrosive, abrasive or slurry-type fluids where standard metal-seated valves wear quickly. We developed our lined ball valve range to solve this problem: combining a robust steel body with a thick, bonded rubber lining and a precision-machined ball to ensure tight shut-off and long service life.

With our rubber lined ball valves, we provide a robust, low-maintenance solution for corrosive and abrasive media.This valve provides bi-directional shut-off and low operating torque. The rubber lining protects both the internal surface of the valve body and the ball’s seating area from corrosion. As a result, process reliability improves and plant safety is enhanced. Whether your plant handles slurry, brine, acidic wastewater or abrasive pulp, our lined ball valves maintain sealing integrity where bare metal valves would fail.

Key Features & Benefits

Full Port Flow: Minimal pressure drop for maximum efficiency.
Bonded Rubber Lining: Protects the valve body and seat area; available in several elastomers.
Corrosion & Abrasion Resistance: Extends service life in aggressive media.
Tight Shut-Off: Precision ball and resilient seat ensure zero-leak performance.
Flexible Operation: Manual lever or gear operator as standard; pneumatic, electric or hydraulic actuators optional.
Compliance: Manufactured and tested according to EN 12266 / API 598 or customer specifications.

Performance & Function

Shut-Off Function: The resilient lined seat compresses uniformly against the lined ball to give bubble-tight sealing in both flow directions.
Energy Efficiency: Full-bore design minimizes pressure loss, lowering pumping costs.
Maintenance: Ball and seat accessible from one side for inspection; lining resists mechanical damage during servicing.
Safety & Environment: No metallic wetted parts exposed to media reduces contamination and extends equipment reliability.

Connection Options

We provide valves with flanged ends as standard for easy installation into process lines. On request we also supply grooved-end or custom drilling patterns to match legacy piping systems. All fasteners are stainless steel or zinc-plated to prevent external corrosion.

Temperature & Pressure

Our standard rubber lined ball valves operate from -20°C up to +120°C at PN10 / PN16 or Class 150 pressure ratings. For higher temperatures or pressures we offer alternative elastomers or special linings.

Materials in Contact with Media

Every wetted surface—valve body, seat area, ball and stem sealing section—is fully lined or isolated from the process fluid. We select the elastomer based on your chemical list to maximize life and minimize risk of swelling or degradation

Typical Applications

Our rubber lined ball valves are installed in:

Chemical processing plants (acids, caustics, brines)
Mining and mineral slurry pipelines
Pulp & paper industry for abrasive pulp streams
Desalination plants and seawater intake systems
Wastewater treatment and neutralization facilities
Fertilizer, salt and sugar plants

Wherever you need a combination of tight shut-off, long life and corrosion protection, this valve delivers.
