Product Specifications

Technical details and manufacturing context for Control Handle/Valve

Definition

This control handle/valve is a mechanical component used in firefighting monitors. It serves as the primary human-machine interface, allowing operators to manually adjust water flow rate, pressure, and directional output during fire suppression operations. The handle is integrated into the monitor's piping system and directly actuates internal valve mechanisms—such as balls, gates, or butterfly discs—to open, close, or modulate fluid passage. Constructed from materials including stainless steel, aluminum alloy, and reinforced plastic, the component is designed for durability in demanding environments. Key parameters, which must be verified for the specific model and application, include an operating pressure range of 1.0–1.6 MPa, a flow capacity of 500–1000 L/min at 1.0 MPa pressure drop, and an operating temperature range of -20 to 80°C (non-freezing environment). Handle torque is ≤20 N·m at maximum pressure, and rotation angle spans 0–270° from full close to full open. Leakage rate is ≤0.01% of rated flow at 1.1× rated pressure, per ISO 5208. Material specifications include CF8M for the body and 316L for trim (ASTM A351), with PTFE seal material (ASTM D3294). Weight ranges from 8–15 kg depending on size. Connection sizes are DN50–DN150, with flanged or threaded ends (ISO 7005), and pressure rating is PN16 (ISO 7268). End connections are flanged with drilling to PN16 (ISO 7005-2). These values are directory references and must be confirmed with the legal manufacturer or supplier for the actual product. Always verify model-specific values and standards before procurement or installation.

Working Principle

Operators manually rotate or manipulate the handle, which mechanically actuates internal valve mechanisms to open, close, or modulate water flow through the monitor's piping system. The handle's movement directly controls the position of internal valve components (such as balls, gates, or butterfly discs) that regulate fluid passage. This mechanical linkage provides precise control over water discharge, enabling operators to adjust flow rate and direction as needed during firefighting operations.
