(CTSD)弹簧薄膜式气动执行器

(CTSD)进口弹簧薄膜式气动执行器 产品应用 Product application

CTSD系列弹簧薄膜回转式执行器，即使在最低的供气压力（1Bar）下，也能通过气、水、基于矿物的液压流体介质来平稳运行。该执行器的工作温度可低至-60℃（-76°F）高达200℃（392°F）。

The CTSD Spring-Diaphragm Rotary Actuators are designed to be used with minimal pressure when necessary and can be operated by air, water, mineral-based hydraulic fluid.Our housing and cover are constructed with a ductile iron/carbon steel casing that is coated with a polyester powder coating. Our independent media room is equipped with a Buna-N diaphragm reinforced with polyamine fabric. These actuators are designed to work in temperatures as low as -60℃ (-76°F) and as high as 200℃ (392°F).

产品特性 FEATURES

1.ISO5211法兰标准 ISO5211 flange standard

弹簧薄膜回转式执行器采用ISO5211国际标准与行业标准相结合的法兰安装尺寸设计，可直接安装在各种类型的阀门顶部 The series offer a combination of different mounting pads that allow you to directly replace existing Spring-Diaphragm Actuator or mount directly to new and existing quarter turn valves.

2.Namur标准连接 Namur Standard connection

弹簧薄膜回转式执行器的附件连接尺寸均按Namur标准设计，可与电磁阀、限位开关、定位器等控制附件直接连接 The Spring-Diaphragm Rotary Actuators are designed to incorporate namur mounting for solenoids, limit switches and positioners.

3.多样化的驱动轴套（可拆卸和更换）  Diversified drive shaft sleeves(Removable&Replaceabe)

弹簧薄膜回转式执行器引入可装拆的驱动轴套技术，能与各种类型驱动阀杆（轴头）的阀门直接进行驱动连接 The Spring-Diaphragm Rotary Actuators feature removable drive bushings which allow you to mount our actuators to a number of different new or existing valve stem configurations in the field for existing valves or for new valve applications.

4.摩擦系数低工作寿命长 Low friction coefficient and long service life

弹簧薄膜回转式执行器采用含油轴承和聚乙烯轴承导向式的隔膜滑行设计技术，有助于降低摩擦系数，确保动作顺畅平稳，延长使用寿命 The Spring-Diaphragm Rotary Actuators feature a rolling diaphragm design with a one piece diaphragm retainer and UMW Polyethylene bearing which helps to obtain longevity of the life cycle and exceptionally smooth actuation due to the low-fric-tion that is produced during operation.

5.可逆的失气开、关调节 Reversible loss of gas on and off regulation

弹簧薄膜回转式执行器采用连接尺寸的对称设计，确保用户在现场就可以快速方便的实现失气关和失气开的转换 The spring film rotary actuator adopts the symmetrical design of the connection size to ensure that the user can quickly and conveniently realize the conversion between air loss off and air loss on site

行程调节 Stroke adjustment

具有双向可调限位装置，可使执行器在全开或全关位置进行<±5°调节 With bi-directional adjustable limit device, the actuator can be adjusted < ± 5 ° in the fully open or fully closed position

机械锁定 Mechanical locking

在弹簧失效时可以被机械锁定 It can be mechanically locked when the spring fails

耐腐蚀性 Corrosion resistance

外部采用防紫外线的聚酯涂层， 所有紧固件采用不锈钢材质，能在恶劣的环境中提供保护，提高耐腐性和耐久性。我们也有聚四氟乙烯涂层可供选择 The exterior is coated with UV resistant polyester, and all fasteners are made of stainless steel, which can provide protection in harsh environments and improve corrosion resistance and durability. We also have Teflon coating to choose from

免润滑油维护 Lubrication free maintenance

执行器在出厂前已做润滑处理，机械转动部位采用含油轴承，在使用过程中无需进一步润滑 The actuator has been lubricated before leaving the factory, and the rotating part of the machine adopts oil bearing, so no further lubrication is required during use
