The VBN2 2-Way Control Ball Valves and VBN3 3-Way Control Ball Valves control hot and chilled water with glycol solutions up to 50% in heating, ventilating, and air conditioning (HVAC) systems to provide two-position or modulating functions. These control ball valves can be ordered alone or with spring return or non-spring return actuators.

The VBN2 2-Way Control Ball Valves and VBN3 3-Way Control Ball Valves control hot and chilled water with glycol solutions up to 50% in heating, ventilating, and air conditioning (HVAC) systems to provide two-position or modulating functions. These control ball valves can be ordered alone or with spring return or non-spring return actuators.

These Honeywell valves control hot and chilled water in HVAC systems, offering two-position or modulating control. They're available with or without actuators and feature a patented seat design for reduced torque. Proper sizing is crucial for efficient operation. The VBN2 Two-Way and the VBN3 Three-Way Control Ball.

They are designed to provide Cv ratings that closely match industry-standard globe valves, and they have equal percentage flow characteristics. A single-style bracket maximizes simplicity and flexibility in mounting spring or non-spring return actuators. The valve bodies are 1/2 in. to 3 in. NPT sizes and use low-torque, low-cost actuators.

3. Eliminate air from system. 4. Two-way valves are marked to show flow direction. IMPORTANT. Flow arrows must point in the direction of the flow for proper operation. NOTE: For three-way valve mounting, see Fig. 3 through 5. 5. Stem rotation: a. For two-way valves: (1) Clockwise to close. (2) Counterclockwise to open. b. For three-way valves:

3-way ball valve, A-B-AB flow, full or reduced port using patented flow control insert. Internal NPT connections. Body Pressure Rating (maximum): 360 psi (2482 kPa) at 250°F (121°C). Medium Temperature Range:-22 to +250°F (-30 to +121°C). Flow Characteristics: 2-way: Equal Percentage with flow control insert. 3-way: Port A to AB: Equal ...

Both Honeywell non-spring return and spring return low torque direct coupled actuators can be utilized with the VBN2 and VBN3 valves. VBN valves use a patented seat design that reduces the torque needed from the actuator. A 35 lb-in. DCA provides sufficient torque to close the valve at rated close-off. (See Table 1.)

只要输入san 不管英文输入还是中文输入 然后又发现打字速度快 且 按到n键 都自动录入zxcvbnm<>?

Both Honeywell fail in place and fail-safe low torque direct coupled actuators can be utilized with the VBN2 and VBN3 valves. VBN valves use a patented seat design that reduces the torque needed from the actuator.

1、这个是键盘连按zxcvbnm，连起来是没任何意思。 是键盘最下一排的字幕，是一个暗号或者密码一类的。 这样做用户名，或者密码，方便输入和记忆。 2、还有一种说法，zxcvbnm=asdfghj 爱上对方，过后就哭了。 asdfghjkl倒过来是LKJHGFDSA。 asdfghjkl的意思是："爱上对方过后就哭了"。 键盘中间都有一排"A、S、D、F、G、H、J、K、L"相连的英文字母，依照拼音，从左点到右，出现的是"爱上对方过后就哭了"。 扩展资料： 每天使用电脑工作，得用键盘输入文字；使 …
