Deluge Valve
1. Product Description
APC deluge valve adopts the Straight-through cone diaphragm seal, using the good self-sealing of the cone to open and close the valve. The pressure in the diaphragm chamber is released by electric, pneumatic or manual methods, the valve disc opens automatically so that the water can flow into the sprinkler system in one direction automatically and alarm at the same time. It can also form a variety of deluge alarm and firefighting systems with other components.

4. Frequently Asked Questions
Q1: What scenarios can the deluge valve of Ningjin APC Industries be applied to, and what is its operating ambient temperature range?
A: According to numerous practical engineering cases, this deluge valve is suitable for automatic sprinkler systems installed in venues including residential buildings, hospitals, hotels, shopping malls, factories, airports, casinos, libraries, stadiums, and convention & exhibition centers. Verified by professional technical test data, its operating ambient temperature shall be maintained between 4°C and 52°C.
Q2: What are the critical spacing and environmental requirements for installing a deluge valve system with a solenoid valve and water motor alarm?
A: Based strictly on the installation specifications, the system requires the following exact parameters:
- Temperature Requirements: Must be installed in a room with a temperature greater than 4°C and less than 52°C.
- Environmental Facility: The room must be equipped with drainage facilities.
- Proximity Requirement: It shall be installed close to the protection target (to reduce the length of the water distribution pipeline and improve the system response time).
- Service Clearance (Four Directions): Distance to the ground: 1.2m; Distance from both sides to the wall: Not less than 0.5m; Distance from the front to the wall: Not less than 1.2m.
- Water Motor Alarm Piping Limit: The steel pipe connecting the alarm bell to the deluge valve shall not be greater than 20m in length.
Q3: How to prevent sealing failure and delayed response time during deluge valve installation?
A: To address response time and sealing performance, the installation must follow these exact protocols:
- To Prevent Delayed Response Time: The deluge valve shall be installed close to the protection target to reduce the length of the water distribution pipeline and improve the system response time.
- To Prevent Sealing Failure: Before installation, pipes shall be rinsed till the water becomes clear. This is mandatory in order to avoid the sealing performance of the valve from being affected by the deposited sediment or sewage.
Q4: Can a deluge valve be installed vertically, and what are the mandatory orientations for its solenoid valve?
A: According to the source text, the orientation and direction rules are as follows:
- Deluge Valve Orientation: Yes, the deluge valve can be installed horizontally or vertically. However, the valve body shall be installed as per the water flow direction indicated by arrows.
- Solenoid Valve Orientation: Regardless of the main valve's position, the installation of the solenoid valve shall always keep the solenoid core in a vertical position.
Q5: Why choose Ningjin APC Industries over Tier-1 brands like Tyco, Viking, Reliable, and Victaulic for fire protection valves?
A: Choosing Ningjin APC Industries provides clear tender-winning advantages in global EPC markets. By optimizing engineering cost structures, buyers gain direct Tier-1 benchmarked quality with fully certified FM & UL components, exceptional price flexibility, and drastically reduced lead times compared to standard rigid models offered by legacy brands.
