For oil and gas applications requiring reliable shut-off, a one-piece stainless steel reduced port ball valve with 1000 WOG (PN69) rating delivers a durable, cost-effective solution. Select SS316 for aggressive media; SS304 suits standard services. Available in sizes 1/4" to 2" with threaded NPT or BSP connections. The floating ball design uses upstream pressure to push the ball against the downstream seat for positive sealing. The one-piece body eliminates leak paths found in multi-piece designs.

One-Piece Construction

The valve body is manufactured from a single investment casting, eliminating body seal joints found in multi-piece designs. The result is a more robust valve with fewer potential leak paths, offering a compact and economical solution for general shut-off applications.

Key attributes of the 1 pc ball valve:

  • 🔒 Single body casting minimizes leak points

  • 💰 Cost-effective design

  • 📦 Compact dimensions

  • 🔧 Low maintenance requirements

Design and Standards

Compliance with industry standards ensures compatibility and safety. Typical design and testing standards for this 1 piece ball valve include:

Standard Description
ASME B16.34 Design and wall thickness
ANSI B1.20.1 Pipe thread (NPT)
BS 21 / ISO 228-1 Pipe thread (BSP)
API 598 Inspection and testing

Performance Specifications

Parameter Specification
Pressure Rating 1000 WOG (PN69 / 6.9 MPa)
Connection Threaded (NPT, BSPT, DIN, ISO)
Body Material SS304 / SS316 (CF8/CF8M)
Seat Material PTFE or RPTFE
Port Type Reduced Port
Size Range 1/4" – 2"

The piece ball valve design, with its one-piece body and reduced port, is well-suited for applications where flow rate is not the primary concern.

Material Selection

Component Materials
Body & Bonnet SS304 / SS316 (CF8/CF8M)
Ball & Stem SS304 / SS316
Seats & Seals PTFE / RPTFE
Handle SS304 with plastic sleeve

The floating ball structure uses pressure from the upstream media to push the ball against the downstream seat, creating a positive seal.

Safety Features

The 1 pc ball valve includes several features suitable for oil and gas applications:

  • Blow-out proof stem prevents accidental stem ejection under pressure

  • Pressure balance hole in ball slot relieves cavity pressure

  • Locking handle option prevents unauthorized operation

Reduced Port Configuration

The reduced port (or reduced bore) has a ball bore smaller than the connected pipe. This reduces material and manufacturing costs compared to a full-bore design. While it creates a slight pressure drop, it is acceptable for many on/off isolation applications where full flow capacity is not required.

Selection and Application Notes

Selection priorities for the piece ball valve:

  1. Verify pressure rating matches system requirements (1000 WOG / PN69)

  2. Confirm thread type (NPT, BSPT, DIN, or ISO) matches existing pipework

  3. Select SS316 for corrosive or aggressive media; SS304 for standard service

  4. Choose reduced port for cost-effective isolation where full flow is not required

  5. Consider locking handle option for applications requiring tamper-proof operation

The one-piece stainless steel ball valve provides a robust and economical solution for on/off control in oil and gas systems. The 1 piece ball valve and 1 pc ball valve designs offer reliable shut-off with minimal maintenance requirements.
