Externally control valve

Product catalog summary

General Specifications:
The externally controlled valve Type 3500 features threaded ends ranging from 3/8" to 2 1/2" and welded ends in DN20, DN40, and DN50. It operates under a pressure of PN16 and is constructed from stainless steel with PTFE seals. The valve supports a working temperature range from -10°C to 220°C and an ambient temperature range from -10°C to 60°C. The actuator is a spring return type, normally closed (NC), with options for normally open (NO) and double acting configurations.

Options:
Additional weld connections are available in DIN 11850-2, DIN 11850-3, or ISO 4200 standards. The seat material can be EPDM, suitable for temperatures between -10°C and 80°C.

Description:
The valve is maintenance-free, easy to install, and energy-efficient. It boasts a long service life due to its robust construction, featuring a stainless steel cylinder and low resistance to prevent water hammer. It is suitable for various applications, including construction, textile, medical, foodstuffs, chemical, and disinfecting industries. The valve can handle media such as water, natural gas, steam (up to 180°C), and mildly corrosive gases and liquids.

Materials:
The valve is composed of various materials, including PC/SS for the top cover, NBR for O-rings, CF8M (1.4408) for the cylinder, piston, and valve body, and PTFE for seals.

Dimensions and Performance:
The valve dimensions vary based on the actuator size and connection type. The Kv-value and control pressure requirements are specified for different sizes, ensuring optimal performance across various applications.
