Valves & Accessories
Valves and system accessories play a critical role in controlling water flow, regulating system pressure, and ensuring proper operation of fire fighting equipment during emergency situations. At Yama Engineering Systems, we provide a carefully selected range of fire protection valves and accessories manufactured in accordance with international fire safety standards (UL/FM).
1-OS&Y valves
OS&Y valves are widely used in fire protection systems as control valves that regulate water flow to sprinkler systems and fire protection networks.
Key Features
* Visual indication of valve position
* Reliable manual control of water flow
* Durable design for fire protection systems
* Easy maintenance and inspection
Typical Applications
* Sprinkler system control valves
* Fire protection risers
* Fire pump discharge piping
* Industrial and commercial fire systems
OS&Y valves are commonly required in fire protection systems designed according to standards such as NFPA 13 and NFPA 24.
Yama Engineering Systems can source and supply a wide range of internationally recognized fire protection brands to meet your specific project requirements. We ensure that all equipment complies with international safety standards and provide full technical support to guarantee seamless integration and reliable operation.
2-Check Valves
Check valves are used in fire protection systems to allow water flow in one direction while preventing reverse flow in the piping network.
These valves are essential in fire pump systems to prevent backflow from the system into the pump or water source. By maintaining proper flow direction, check valves protect system components and ensure stable hydraulic performance.
Key Features
* Prevent reverse water flow
* Protect fire pump equipment
* Maintain system pressure stability
* Reliable automatic operation
Typical Applications
* Fire pump discharge lines
* Fire protection risers
* Water supply systems
Yama Engineering Systems can source and supply a wide range of internationally recognized fire protection brands to meet your specific project requirements. We ensure that all equipment complies with international safety standards and provide full technical support to guarantee seamless integration and reliable operation.
3-Flow Meters
Flow meters are important devices used in fire pump systems to measure the water flow rate during testing and commissioning procedures.
They allow engineers to verify that the fire pump delivers the required flow and pressure according to system design and applicable fire protection standards.
Flow meters are commonly installed on fire pump test lines to evaluate pump performance during acceptance testing and periodic inspections.
Key Features
* Accurate flow measurement
* Essential for fire pump testing
* Helps verify pump performance
* Supports system commissioning and maintenance
Typical Applications
* Fire pump testing systems
* Pump performance verification
* System commissioning procedures
Yama Engineering Systems supplies GVI flow meters as part of our fire pump packages, ensuring seamless integration, accurate system monitoring, and full compatibility with the pumps we provide. Additional international brands can also be sourced upon request to meet specific project requirements.
4-Main Relief Valves
Main relief valves are pressure control devices used in fire pump systems to prevent excessive pressure buildup in the fire protection network.
These valves automatically release water when the system pressure exceeds the allowable limit, protecting pipes, valves, and other system components from damage.
Main relief valves are particularly important in fire pump installations where pressure surges may occur during pump operation.
Key Features
* Automatic pressure relief
* Protects piping systems and equipment
* Prevents overpressure conditions
* Enhances system safety and reliability
Typical Applications
* Fire pump discharge systems
* High-pressure fire protection networks
* Industrial fire protection installations
Yama Engineering Systems supplies CLA-VAL flow meters as part of our fire pump packages, ensuring seamless integration, accurate system monitoring, and full compatibility with the pumps we provide. Additional international brands can also be sourced upon request to meet specific project requirements.
5-Siamese Connections
Siamese connections, also known as Fire Department Connections (FDC), allow fire brigade teams to connect their fire engines directly to the building’s fire protection system.
This connection enables firefighters to supply additional water to the sprinkler or standpipe system during fire emergencies, ensuring sufficient water supply even if the building’s primary water source becomes insufficient.
Siamese connections are typically installed on the exterior wall of buildings for easy access by emergency response teams.
Key Features
* Provides auxiliary water supply to fire systems
* Allows connection of fire department pumpers
* Enhances fire fighting capability during emergencies
* Designed for quick access by firefighters
Typical Applications
* High-rise buildings
* Commercial complexes
* Industrial facilities
* Large public buildings
Yama Engineering Systems can source and supply a wide range of internationally recognized fire protection brands to meet your specific project requirements. We ensure that all equipment complies with international safety standards and provide full technical support to guarantee seamless integration and reliable operation.
6-Fire Hydrants
Fire hydrants are critical components of fire protection infrastructure, providing accessible water outlets for firefighting operations.
They allow fire brigade teams to quickly connect hoses and obtain a reliable water supply during fire emergencies. Fire hydrants are commonly installed in outdoor locations such as roads, industrial yards, and facility perimeters.
Hydrants are designed to deliver high water flow rates and are built to withstand harsh environmental conditions.
Key Features
* High-capacity water discharge
* Durable construction for outdoor environments
* Quick connection for fire brigade hoses
* Reliable emergency water supply
Typical Applications
* Industrial facilities
* Warehouses and logistics centers
* Commercial developments
* Infrastructure and public areas
Yama Engineering Systems can source and supply a wide range of internationally recognized fire protection brands to meet your specific project requirements. We ensure that all equipment complies with international safety standards and provide full technical support to guarantee seamless integration and reliable operation.
