Exploded view of red diaphragm control valve

Dorot Series 100 Diaphragm Valve

The Dorot Series 100 valves feature a reinforced diaphragm as the only moving part, delivering precise and reliable flow control while preventing backflow and water hammer. They can be operated using line pressure or an external source, making them ideal for water supply, firefighting, industrial, sewage, and irrigation systems.

The valve provides low pressure loss and smooth modulation from no-flow to full-flow. It is available in cast iron, bronze, or ductile iron with multiple diaphragm options, compatible with 2-way or 3-way pilot systems, including float- or pressure-actuated control, and comes in sizes ranging from 20–600 mm with threaded, flanged, or grooved connections, ensuring efficient, accurate, and dependable performance for critical applications.

Heavy-duty blue valve with diaphragm and pressure regulator for industrial process regulation

 Pressure Reducing Valve – LQM-8090-01

The Pressure Reducing Valve automatically reduces high inlet pressure to a steady, lower downstream pressure—maintaining accuracy regardless of flow or inlet fluctuations. This pilot-operated regulator holds downstream pressure to a pre-set limit and closes drip-tight when the limit is exceeded.

Specifications:

  • Body: Cast iron, powder-coated
  • Diaphragm: Reinforced natural rubber
  • Fastenings & Spring: Stainless steel
  • Pressure Rating: 16 bar
  • Minimum Opening Pressure: 7 bar
  • Velocity Range:5–8 m/s
  • Maximum Temperature: 70 °C
  • Connections: 25–65 mm BSP threaded; 80–200 mm flanged PN16 / AS4087 PN16 / ANSI 150

Optional Features:
Closing speed control, X46A flow clean strainer, isolation valves, flow controls (opening/closing), check valves with isolation, pressure gauge, and “Y” strainer

 

Durable check valve ensuring reliable backflow prevention in industrial operations

 Check Valves

Cast Iron Wafer Check Valve – WCV1

The WCV1 is a maintenance-free, dual-disc wafer check valve that prevents backflow and water hammer while ensuring low flow resistance. Made from cast iron, nitrile, and stainless steel, it performs reliably in demanding conditions. Suitable for vertical or horizontal installation, it handles pipe sizes 50–600 mm, pressures up to 24 BAR, and temperatures from -10°C to 80°C. Larger sizes include eye bolts for easy handling.

Key Features:

  • Quick-close discs prevent backflow and water hammer
  • Low flow resistance
  • Maintenance-free and durable
  • Easy to install
Liquimech valves including butterfly, gate, ball, and diaphragm types for precision flow management and industrial process optimisation

Industrial Valves for Reliable Flow and Maximum Efficiency

Liquimech offers a comprehensive range of high-performance valves, including butterfly valve, gate valve, ball valve, and diaphragm valve, designed to meet the demands of critical industrial processes. Built for durability, efficiency, and versatility, these valves provide reliable flow control, prevent backflow, and reduce pressure loss across a wide range of applications.

Electric actuator and valve combination for pipeline applications

We Make Valve Automation Easy                                                     

Electric Quarter-Turn Actuators

Electric quarter-turn actuators provide a torque range of 35 N·m to 4500 N·m. The design is based on a self-locking worm drive principle, ensuring a smooth, reliable, and durable drive system.

Features

  • 30% duty cycle at rated torque.
  • Self-locking function.
  • Built-in thermal protection prevents motor burnout: 125°C (257°F) for AC motors and 90°C (194°F) for DC motors. (The 75% duty cycle actuator uses a DC motor.)

What Is a Valve Actuator?

A valve actuator is a device that automatically opens and closes control valves to regulate fluid flow in systems. Valves with actuators are often called automatic valves, and electrically operated ones are known as electric valves.

Think of it as the muscle that opens, closes, or modulates valves based on control signals, eliminating the need for manual operation.

Uses of Valve Actuators

Valve actuators enable precise automated fluid control across a wide range of applications. They are commonly used in industrial processes to regulate pipelines, chemical flows, and water systems, ensuring efficient, safe, and reliable operation.

How Valve Actuators Work

Electric actuators convert electrical energy into precise rotational or linear motion. Electric valve actuators provide accurate control over valve operation. These actuators are energy-efficient and require only a power source to function, making them suitable for applications demanding precision and repeatability.

Testimonial

domeshelter

We have been dealing with Liquimech since they started out, and they have never let us down. With both our companies being Australian owned and operated, our values align perfectly, we pride ourselves in manufacturing high quality Australian Made products. I highly recommend Liquimech and wouldn’t think to go anywhere else, appreciate all you have done and look forward to what is to come!

The standpipe is working well, going good. The pump allows for fast truck fill, all comes down to the size of the pump.
Francis
Director - Doolee Construction
Italia Stone Group Logomark

It’s exceeded our expectations. High quality, we don’t need any counter weights and it’s easy to set up. It’s been in operation for 6 months now with no hassles, we’ve got quite a substantial pump driving water to the standpipe and we haven’t any issues. Overall quality & reliability supplied by Liquimech has been very impressive.
