Montalvo Montalvo tension controllers Z4UD and Z4UL.

Montalvo authorized distributor of Montalvo tension controllers Z4UD and Z4UL. We also distribute the upgraded D-3400Pce-UW-NILL tension controller Z4UDAN-B PCB version (minor program differences, but basic functions are met; it's an upgrade from the D3400).

We offer original Montalvo Z4 tension controllers at discounted prices, with fast delivery.

We can provide Montalvo controller origin certificates, product quality certificates, and customs declarations. The recently developed Montalvo Z4™ tension controller is an analog Montalvo controller using PID control, providing precise automatic tension control. Progressive PID adjustment automatically compensates for roll diameter.

The Montalvo Z4 tension controller is widely used in the winding industry for unwinding, rewinding, and intermediate processes, forming closed-loop control. Various Montalvo tension controller models are available, including RL, UL, UI, UD, and NL. 1) Montalvo tension sensor function: Montalvo tension sensors are generally used in pairs.

The tension signals from two Montalvo tension sensors, when combined, represent the roll tension. The four strain resistors of the two tension sensors form a Wheatstone bridge, which operates at ±2.5V.

Changes in coil tension cause corresponding changes in the bridge resistance, which in turn cause changes in voltage. coil.

2) Montalvo Brake Function: The Montalvo Z4 controller can control one or more Montalvo brakes, converting the pneumatic output via an electro-pneumatic converter into a torque output. This torque then correspondingly changes the coil tension.

3) Converter Function (Montalvo Brake): The Z4 controller can be used to adjust pneumatic or electric brakes.

When adjusting a pneumatic brake, the 4-20 mA output current is proportionally converted into an airflow output of 0-75 PSI (0-6 bar) via an electro-pneumatic converter. When adjusting an electric brake, a voltage converter is required.

Depending on the application, other types of converters can also be selected.

4) Coil Diameter Signal: It is recommended to use the coil diameter signal to optimize the tension system. Two proximity switches or analog signal devices such as ultrasonic probes can be used on the coil to acquire the signal and calculate the coil diameter.

5) Automatic Mode (Closed-Loop): The operator sets a tension value in automatic mode on the controller.

The controller compares the actual value with the set value and adjusts the output until the actual tension value equals the set tension value. 6) Manual Mode (Open-Loop): The operator sets the required brake air pressure value via a manual potentiometer.

The tension of the roll material is also detected and displayed on the Montalvo tension indicator.

However, in this mode, the tension is not automatically adjusted. To maintain stable tension, the operator needs to continuously adjust the manual potentiometer. Montalvo is a distributor of Montalvo tension controllers (Z4UD and Z4UL).

Montalvo Holdings specializes in roll material tension analysis, upgrades, and maintenance of customers' roll material tension control equipment.

For over 60 years, Montalvo has provided manufacturing, integration, and after-sales service for a wide range of tension control needs, covering industries such as aluminum foil, nonwovens, and plastic film, as well as packaging, pharmaceuticals, and high-tech applications.

Montalvo products include electronic tension control devices, Montalvo tension sensors, Montalvo indicators, Montalvo brakes, Montalvo clutches, and safety chucks. Montalvo products are manufactured in the USA and serve customers worldwide through its extensive sales and after-sales service network.

began his career as a manufacturer's agent in New York in. 1947. In 1970, at the age of 57, Mr. Montalvo developed the world's first prototype of an air-cooled dual-disc brake. In 1976, Mr. Montalvo founded the Montalvo Corporation in Portland, Maine, USA.

By December 1978, the factory had rapidly tripled in size. In 1984, with continued growth in market demand, the factory expanded again. In May 2001, the company expanded once more, moving from Portland to its Industrial Product Innovation Base in Gorham, Maine, USA.

At this time, Montalvo had a wholly-owned factory in Denmark, a joint venture factory in Japan, and a licensed production plant in India.

In 1993, Montfort acquired all shares of Danarota Technic and its three existing companies: Montalvo A/S (Montalvo's wholly-owned manufacturing company in Europe), DRT Electronic ApS (an electronics company jointly owned by Montfort and Danarota), and Danarota Technic A/S, merging them into Montfort's European branch.

To meet market needs, a sales branch was established in Germany, and Montfort's sales in the European market expanded significantly, successfully developing and operating in several new markets including Eastern Europe, Southern Europe, Central Asia, and the Middle East.

In January 2009, Montfort's branch in Denmark was officially named Montfort (Europe).

Products manufactured at Montfort (Europe) are shipped from Denmark to customers worldwide. Sales and service in the European market are handled by its intercontinental sales department's network system.

At the end of 2007, in response to the booming development of the Asian market and to meet the needs of customers in the region, Montfort Holdings established Montfort (Shanghai) Trading Co., Ltd. in China.

With its headquarters in and offices in Beijing, Xi'an, and other locations, Montfort's sales and technical service network covers every major market, ensuring that all Montfort users enjoy the same comprehensive and first-class service while owning its cutting-edge technology products.
