Description
Overview:
The Inline Lever Ball Valve 1" BSP Female Thread is a compact shut-off valve for clean, reliable control of fluid flow in pipework and machinery. It has a robust metal body with a corrosion‐resistant finish and a red lever handle for quick, positive operation. Both ends are 1" BSP female (equivalent to 25.4 mm), making it straightforward to join to standard UK pipe fittings and hoses. The inline, straight‐through form factor suits tight spaces and helps simplify routing on pumps, tanks, manifolds, and workshop systems. Commonly used around construction and garden machinery, plant equipment, and static installations, it provides a simple quarter‐turn open/close action for isolating lines during maintenance or operation. Supplied under MPN 850 100 for easy identification in spares lists and site inventories.
Key Features:
- 1" BSP female thread at both ends (25.4 mm) for direct connection to standard UK fittings and hose tails
- Inline, female/female layout for easy integration in straight runs of pipe or hose assemblies
- Quarter‐turn lever action for fast isolation and clear open/closed status
- Durable metal construction with a corrosion‐resistant finish for long service life
- Bright red lever handle for easy identification and confident grip, even with gloves
- Smooth, positive operation helps reduce downtime during maintenance and repairs
- Suited to domestic, trade, and light industrial systems handling general fluids
- Compatible with common installation practices such as use of thread sealant or PTFE tape on BSP male counterparts
Typical Applications:
Used for isolating sections of pipework on pumps, tanks, and manifolds; diverting or stopping flow to taps, hose reels, irrigation zones, and washdown lines; controlling services on machinery skids and plant rooms; and providing service shut‐offs on compressors and workshop equipment. Ideal where a straightforward quarter‐turn valve is needed to manage non‐potable water and general service lines in site, workshop, and agricultural settings.
Also known as:
Often referred to as an isolation valve, quarter‐turn valve, stop valve, service valve, cut‐off valve, or line valve. You may also see it described as a female/female inline valve or 1 inch BSP inline isolation valve in parts lists and plumbing catalogues.
