Spring Loaded Ball Valve

 

Spring Loaded Ball Valve, offering secure sealing and efficient flow regulation in fluid systems with spring-assisted ball movementProduction Overview

The Spring Loaded Ball Valve from Vcore Valves is designed for applications that require reliable sealing and automatic operation. The valve incorporates a spring-loaded mechanism that helps maintain consistent pressure on the ball, ensuring the valve’s sealing surface remains tightly engaged with the seat during operation. This mechanism reduces wear and improves valve longevity, making it ideal for high-pressure and high-cycle applications.

Key Features

  • Spring-Loaded Design – Ensures consistent pressure on the ball for reliable sealing and longer service life

  • Full Bore Flow – Minimizes pressure drop and allows for higher flow capacity

  • Durable Construction – Made from stainless steel, carbon steel, and alloy steel for corrosion resistance and high strength

  • Automatic Sealing – Spring mechanism maintains tight sealing during operation, reducing wear and leakage

  • High-Pressure & Temperature Resistance – Suitable for demanding applications with high pressure and temperature fluctuations

  • Compact and Reliable – Ideal for tight installations and high-cycle operations with minimal maintenance requirements

  • Versatile Actuation Options – Manual, pneumatic, and electric actuators available for automated control

  • Global Standards Compliance – Manufactured in accordance with ANSI, API, ISO, and AWWA standards

The Spring Loaded Ball Valve operates by utilizing a spring mechanism that applies continuous pressure on the valve’s ball, ensuring the ball stays tightly pressed against the seat. This design is crucial for applications where reliable sealing is required under fluctuating pressures, especially in environments with high or varying fluid flows.

The valve’s ball design enables smooth, quick operation for opening and closing. In the open position, the full-bore design allows unrestricted fluid flow with minimal resistance, while in the closed position, the spring-loaded mechanism ensures a tight seal to prevent leakage, even under pressure fluctuations. The non-rising stem (NRS) design saves space, making it suitable for installation in confined spaces.

Constructed from corrosion-resistant materials such as stainless steel, carbon steel, and alloy steel, the valve provides superior performance even in harsh environments. It is commonly used in industries such as oil & gas, chemical processing, water treatment, and HVAC systems, where precise flow control, durability, and minimal maintenance are critical.

The spring-loaded ball valve is designed with a full-bore flow that minimizes pressure drop and ensures efficient fluid flow. Its compact design is ideal for tight spaces, while the spring mechanism guarantees reliable sealing even under fluctuating pressure conditions.

Application

  • Oil & Gas – Isolation and flow control in pipelines, refineries, and offshore platforms
