Gauges & Valves

About Gauges & Valves

Gauges and valves are precision components essential for maintaining and controlling pressure sprayer systems used across agricultural, horticultural and industrial applications. MyToolShed.co.uk supplies quality replacement gauges and valves from trusted manufacturers including Solo and Hozelock, designed to monitor pressure accurately and provide reliable flow control. These components ensure your spraying equipment operates safely and efficiently, whether you're applying herbicides, pesticides or cleaning solutions.

A functioning pressure gauge allows you to maintain optimal working pressure for consistent application results, whilst a dependable shut-off valve prevents drips and unwanted discharge between uses. Manufactured from corrosion-resistant materials with robust construction, these components are engineered to withstand professional use and handle various chemical formulations. Quality replacement gauges and valves extend the operational lifespan of your sprayer system and maintain professional application standards.

Applications

Gauges and valves for pressure sprayers are used by professionals and enthusiasts across numerous sectors:

• Agricultural contractors and farmers applying herbicides, pesticides and liquid fertilisers
• Groundskeepers and greenkeepers maintaining sports pitches, golf courses and public parks
• Horticultural professionals working in nurseries, garden centres and landscaping businesses
• Pest control technicians treating commercial and residential properties
• Facilities maintenance teams responsible for weed control and exterior cleaning
• Local authority workers managing verge maintenance and public spaces
• Railway maintenance crews controlling vegetation along tracks and infrastructure
• DIY enthusiasts and allotment holders maintaining gardens and growing areas

Choosing The Right Gauges & Valves

Compatibility: Always verify that replacement components match your specific sprayer model. Solo and Hozelock parts are engineered to precise specifications, so check your sprayer's make and model designation (Plus, Pro or Viton) before purchasing. Thread sizes and connection types must match your existing system.

Pressure Range: Ensure gauges cover your sprayer's operating range. Most backpack and compression sprayers operate between 2-6 bar, whilst more powerful equipment may require gauges rated to 10 bar or higher. Choose gauges with clear, easy-to-read markings.

Chemical Resistance: Consider the chemicals you'll be spraying. If working with aggressive solvents or petroleum products, ensure valves and gauge seals are manufactured from chemically resistant materials such as Viton, as standard EPDM or nitrile seals may deteriorate.

Build Quality: Professional-grade components from established manufacturers available at MyToolShed.co.uk offer superior durability. Look for brass or stainless steel construction in valve bodies and corrosion-resistant gauge housings.

Safety Information

Always fully depressurise your sprayer system using the pressure release assembly before removing or replacing any components. Pressurised liquid can be forcefully discharged, potentially causing injury or chemical exposure. Regularly inspect pressure gauges for accuracy and damage—a faulty gauge may provide false readings leading to over-pressurisation and equipment failure. Ensure all connection fittings are properly tightened to prevent leaks, but avoid over-tightening which may damage threads. When working with chemical sprayers, always wear appropriate PPE as specified by COSHH guidelines, including chemical-resistant gloves and eye protection.

Frequently Asked Questions

How often should I replace my pressure gauge?
Replace your gauge if it shows damage, the needle becomes stuck, the face fogs up, or readings appear inaccurate. Professional users should consider annual replacement as part of routine maintenance to ensure application accuracy and prevent over-pressurisation.

Are Solo and Hozelock parts interchangeable?
Generally no—parts are not interchangeable between brands. Solo components are designed for Solo sprayers, and Hozelock parts for Hozelock models. Always verify compatibility with your specific sprayer model before purchasing replacement gauges or valves.

What pressure should I maintain in my backpack sprayer?
Most backpack compression sprayers operate optimally between 2-3 bar for general applications. However, always consult your sprayer's manual and the chemical manufacturer's recommendations, as some formulations require specific pressure ranges for effective application.
