Product Overview

The 2-piece carbon steel ball valve is designed for industrial pipeline systems requiring reliable shut-off performance, mechanical strength, and maintainable construction under continuous operating pressure.
Its split-body structure (two-piece bolted design) allows internal component servicing without replacing the entire valve, making it suitable for long-life pipeline installations where maintenance access and downtime control are critical.
Typical applications include industrial utility systems, process piping, water treatment facilities, compressed air networks, and non-corrosive or mildly corrosive fluid transfer lines.

Structural Design Features

1. Two-Piece Body Construction for Maintainability
The valve body consists of two bolted sections, allowing access to internal components (ball, seats, seals) during maintenance.
Engineering value:

Reduces pipeline downtime during repair cycles
Enables seat and seal replacement instead of full valve replacement
Suitable for long-service industrial installations

2. ASTM A216 WCB Carbon Steel Body
The valve body is manufactured from ASTM A216 WCB carbon steel, commonly used in industrial pressure-containing components.
Material characteristics:

High tensile strength suitable for pressure systems
Good resistance to mechanical impact and thermal cycling
Stable performance under continuous operating loads

3. Full Bore / Reduced Bore Configuration Options
Two flow design options are available:

Full Bore: Inner diameter matches pipeline bore, minimizing pressure drop
Reduced Bore: Compact design for cost optimization and space-saving installations
This allows EPC contractors and distributors to standardize inventory across different pipeline sections.

4. Precision Machining & Sealing System
Reliable shut-off performance is achieved through controlled manufacturing precision:

CNC machining for spherical ball finishing
Tight dimensional tolerance control on sealing interfaces
PTFE / RPTFE seats designed for low friction and stable sealing under pressure variation

Quality Control & Inspection System

Each valve is manufactured under strict quality control procedures:

100% dimensional inspection (face-to-face, flange alignment, bore concentricity)
Hydrostatic shell and seat pressure testing in accordance with API 598
Torque and operational smoothness testing for manual and actuator versions
Material traceability supported by heat number tracking
EN 10204 3.1 Mill Test Certificates (MTC) supplied with shipment

Industrial Applications

This valve is suitable for on/off isolation service (not throttling control) in:

Oil & gas auxiliary pipelines
Industrial chemical transfer systems (non-aggressive media)
Water treatment and distribution networks
Compressed air and utility steam lines
Power plant cooling and auxiliary systems

Selection Guidelines

Working Condition	Recommended Configuration
Standard water / oil service	WCB + PTFE seat
Higher pressure systems	Class 300 / 600 + reinforced seat
Elevated temperature	RPTFE or graphite-based sealing option
Mild corrosive media	Consider CF8 / CF8M stainless steel series
Frequent cycling service	Reinforced stem + upgraded sealing system

Reduced replacement frequency
Lower maintenance downtime
Serviceable internal components
Longer operational lifecycle under industrial conditions

FAQ

Q: What is the difference between 1-piece, 2-piece, and 3-piece ball valves?

A: 1-piece: Non-serviceable, lowest cost, limited maintenance capability
2-piece: Balance between structural strength and maintainability
3-piece: Fully serviceable, highest flexibility for high-end industrial maintenance environments

Q: Can this valve be used in high-pressure systems?

A: Yes. When configured with Class 300 or Class 600 pressure ratings and appropriate sealing materials, the valve is suitable for medium to high-pressure industrial pipelines. Final selection should be based on actual temperature and media conditions.

Q: Is it suitable for corrosive media?

A: Standard WCB carbon steel is recommended for non-corrosive or mildly corrosive fluids. For aggressive chemical media, stainless steel (CF8 / CF8M) or internal coating solutions are recommended.

Q: What documents are provided with shipment?

A: Each shipment includes:
Commercial invoice and packing list
Pressure test reports (API 598 compliant)
EN 10204 3.1 material certificates
Traceability documentation (heat number tracking)

Q: Do you support OEM and distributor cooperation?

A: Yes. We support:
OEM branding (logo casting, tags, packaging)
Distributor private label supply
Long-term contract manufacturing
Customized engineering configurations
