Product Overview The Manure Slurry Pinch Valve is intended for isolation or specified flow-control duties in pumpable manure and livestock wastewater pipelines. When open, the flexible sleeve provides an unobstructed flow path. When actuated, the sleeve is compressed to restrict or stop flow. This arrangement keeps the process medium within the sleeve and provides a practical service point in commercial pig farm manure handling systems.
Key Features
  • Full-bore flow path when fully open, subject to the selected valve design.
  • Flexible sleeve closes around the medium, making the design suitable for many solids-bearing slurries.
  • Process contact is concentrated at the replaceable sleeve in applicable designs.
  • Manual, pneumatic, or electric operation can be evaluated according to project requirements.
  • Sleeve and body options can be matched to manure composition, cleaning chemicals, ambient conditions, and duty cycle.
Structural Components The main components are a valve body, flexible elastomer sleeve, end connections, and an operating mechanism. Mechanically operated designs use a closing mechanism to compress the sleeve; air-operated designs apply controlled air pressure around it. Actuator, position feedback, and control accessories are specified only where required by the farm's automation system.
Working Principle With the valve open, slurry passes through the sleeve. Actuation compresses the sleeve to reduce the opening or isolate the line; releasing the closing force allows the elastic sleeve to reopen. The exact closing method depends on the selected valve construction. A dedicated control configuration is required if the valve will be used for repeated throttling rather than occasional isolation.
Technical Specifications
  • Nominal size and end standard: According to project requirements and mating pipework.
  • Sleeve material: Selected for slurry abrasion, chemical compatibility, temperature, and operating pressure.
  • Body construction: Available upon request for the selected valve design.
  • Pressure and temperature ratings: Confirmed for the complete valve assembly before supply.
  • Actuation and controls: Customizable according to isolation or control duty.
  • Outdoor suitability: Designed according to local climate and farm conditions.
Applications Potential locations include manure transfer pump discharge lines, branch lines to slurry storage, solid-liquid separation systems, livestock wastewater treatment equipment, and maintenance isolation points. In pig farm construction, valve access and pipe support should be coordinated with service corridors, equipment rooms, and steel structure building layouts.
Customization Options Valve size, sleeve compound, end connection, body arrangement, actuator, and position indication can be reviewed against the project specification. Please provide pipeline diameter, operating and surge pressure, fluid composition, temperature, expected cycling frequency, and whether the valve is intended for shut-off or modulating control. Vacuum service must be identified so an appropriate sleeve design can be assessed.
Installation & Maintenance Install the valve using the selected manufacturer's instructions and compatible piping connections. Support adjacent pipework so external loads do not distort the valve, and leave sufficient clearance for actuator access and sleeve replacement. Isolate and depressurize the line before service. Inspect the sleeve for wear, loss of elasticity, or leakage, and check the actuator and controls at intervals suited to the farm's operating conditions.
Product FAQ

Can the valve handle manure with solids?
Pinch valves are used for solids-bearing slurries, but the valve size, sleeve, and duty must be checked against the actual particle size, fiber content, and flow conditions.

Can it be automated?
Pneumatic or electric actuation may be specified, together with suitable controls and position feedback.

Is the same sleeve suitable for every manure line?
No. Sleeve selection depends on the medium, pressure, temperature, cycling frequency, and whether the line operates under vacuum.
