Product details

In industrial piping systems, especially those with high explosion risks or strong corrosive chemicals, choosing the right control valve is a major challenge for engineers. Metal valves corrode easily, while electric valves raise concerns about electrical sparks.

The current optimal solution is the Hayward Pneumatic Actuated Plastic Butterfly Valve – durable technology from the USA, officially distributed and technically supported by Origin Pipe JSC.

1. Why Choose Hayward Pneumatic Butterfly Valves?

The combination of a premium plastic butterfly valve body and a pneumatic actuator creates an automated device with three outstanding advantages:

  • Absolute Safety: Unlike electric valves, pneumatic valves operate entirely on air pressure, using no electricity at the valve site. This eliminates 100% of short-circuit or spark risks, making them perfect for hazardous areas (Zone 1, Zone 2) in chemical and oil refinery plants.
  • Immunity to Corrosion: The valve body and disc are injection-molded from high-grade UPVC or CPVC. These materials are completely inert to acids, alkalis, salt, and solvents—factors that typically "kill" cast iron or stainless steel valves after just a few months.
  • High-Speed Operation: Hayward’s Actuator allows for almost instantaneous opening and closing (1-2 seconds), meeting the requirements for emergency shut-off or high-frequency cycling systems.

2. Operating Principles: Single Acting vs. Double Acting

Depending on the safety requirements of the system, you can choose between two types of actuators:

  • Double Acting (DA): Requires air pressure for both the opening and closing cycles. This type is energy-efficient but will stay in its last position if the air supply is lost.

  • Single Acting (Spring Return - SR): Uses air pressure to open and an internal spring to close (or vice versa). This is a "Fail-Safe" design—if the air supply fails, the spring automatically returns the valve to a safe state (usually closed), preventing chemical spills.

5. Troubleshooting & Maintenance Guide

To help customers operate their systems efficiently, the Origin Pipe technical team has compiled a quick checklist of common problems:

Common Issues

Likely Causes

Solution

Valve does not open/close

1. Air pressure is too low (<60 PSI).

2. Burnt solenoid coil.

1. Check compressor and air lines.

2. Replace the coil or solenoid unit.

Sluggish operation

1. Clogged air filter.

2. Worn cylinder seals causing leaks.

1. Clean the Air Filter.

2. Contact Origin Pipe for a Seal Kit replacement.

Water leakage when closed

Liner is torn or worn due to debris.

Disassemble, clean the pipe, and replace the liner.

Air lost but valve doesn't close (Spring type)

Springs are broken or weakened over years of use.

Major overhaul or Actuator replacement required.

Pro Tip: Always ensure the air supply to the valve is Clean and Dry. Moisture in compressed air is the leading cause of internal spring rusting.
