Mais Leveza e Precisão

Com os Hearken Flow Atuadores Manuais de Engrenagem, você sente a diferença desde o primeiro giro do volante. A estrutura de manual caixa de engrenagens foi projetada para multiplicar o torque com mínima força, tornando o acionamento mais suave mesmo em válvulas de grande diâmetro ou alta pressão.

As engrenagens modulares autolubrificadas garantem operação contínua, sem travamentos, enquanto o Eixo sem-fim com travamento automático impede o retorno inesperado, mantendo a posição estável e segura.

Com isso, você tem menos esforço físico, mais precisão e total confiança na operação — mesmo em processos exigentes de água, esgoto, mineração ou gás.

Customization & Product Advantages

Self-Locking Safety

Hearken Flow worm gear transmission has self-locking characteristics, the worm lead angle is small, only the worm can drive the worm wheel, which can prevent the equipment from reversing, and is often used in lifting operations and other scenarios.

Quiet Transmission

Spiral transmission, the two-wheel tooth surface line contact, smooth operation, low noise, suitable for precision instruments, office equipment and industrial sites with high noise requirements.

Compact and Small

Compact design, small space can achieve a large transmission ratio, when transmitting the same power torque, it occupies less space than other transmission methods, suitable for ships, aerospace and small automated production lines.

Heavy-duty and Durable

Worm wheels and worms are made of high-quality materials and advanced processes, hardened, high strength, wear resistance, can withstand heavy loads, and operate stably in heavy machinery such as mines and construction.

Alta Resistência em Ambientes Severos

Os Hearken Flow Actuadores de engranajes manuales foram criados para suportar ambientes úmidos, com poeira ou agentes corrosivos. A construção robusta e as vedações de anel O-ring mantêm o interior limpo, evitando desgaste precoce e garantindo longa vida útil.

Ductile Iron Wafer Butterfly Valve with Gear Box

Operação Suave e Confiável

O sistema de rolamentos axiais de alto desempenho e engrenagens autolubrificadas assegura movimentos sem vibrações ou travamentos. Mesmo após anos de uso, o acionamento continua leve, silencioso e preciso, ideal para aplicações industriais contínuas.

Confiabilidade Duradoura Mesmo Nas Condições Mais Exigentes

Proteção Contra Corrosão e Trava Segura

A carcaça com proteção IP65 e o dispositivo de travamento mecânico mantêm o funcionamento seguro em áreas externas e plantas industriais. Você evita falhas por oxidação, mantendo controle total da válvula com segurança extra.

Evita Travamentos e Manutenção Frequente

Com as superfícies internas tratadas e conexões de lubrificação acessíveis, o Atuador para válvula manual não sofre com ferrugem nem emperramentos. Isso reduz a necessidade de manutenção, economizando tempo e custo de operação.

Design Features & Configuration Options

Appearance Design

HEARKEN FLOW considers the space size under different working conditions and deliberately chooses a compact, durable and reliable design, which allows you to flexibly apply it in different working conditions.

Body Material

HEARKEN FLOW can provide aluminum alloy, stainless steel and plastic cylinder materials. If you want to apply it to some heavy-duty industrial environments with strong corrosiveness, then HEARKEN FLOW’s stainless steel pneumatic actuator is definitely your first choice.

Accessory Selection

HEARKEN FLOW also provides one-stop supporting services. Accessories such as pneumatic positioners, limit switches, solenoid valves, air filters, etc. can be installed for you, so that you can receive the goods with peace of mind and effort. There is no need to deal with tedious multi-person communication and shipping integration.

Multi-angle Selection

In order to adapt to the valves you don’t use, our HEARKEN FLOW can provide pneumatic actuators with different angles. For example, you can use the 90° pneumatic actuator on ball valves and butterfly valves; if you want to use it on three-way valves or valves that need to be diverted in some special occasions, then you can choose HEARKEN FLOW 120° or 130° pneumatic actuators.

Available In Spring Return Or Double Acting Configurations

HEARKEN FLOW offers pneumatic actuators in spring return and double acting configurations, with spring return configurations ensuring system safety and double acting configurations providing higher thrust and torque to meet a variety of different industrial needs.

Professional Customization Team

We have a professional customization technical team. You can provide design drawings or communicate with our technical manager to make customization requirements. Hearken Flow will provide you with the most cost-effective solution in terms of price and suitability for your needs.
