ROSS-Safety-related valves

Product catalog summary

Regulations for Workplace Safety
The document outlines OSHA regulation (29 CFR 1910.147) for controlling hazardous energy during machine maintenance. Key requirements include disconnecting energy sources and locking them to prevent reactivation.

Pneumatic Energy Control

Shut-off Valve: Each equipment must have a shut-off valve to isolate it from its air supply.
Lockable Valve: The valve should be lockable with a padlock.
Pressurized Air: Must be relieved by exhausting to the atmosphere.
Tagout vs. Lockout: Tagout can replace lockout if it provides equivalent safety.

ROSS L-O-X® and EEZ-ON® Products
These products comply with OSHA and EN 1037 regulations, providing shut-off control, lockability, and exhaust functions. The L-O-X®/EEZ-ON® valve combines shut-off and soft start functions.

Affected Parties
Approximately 631,000 businesses, mainly in manufacturing and servicing, are affected. Equipment operators and service personnel are at high risk.

Benefits
The regulation aims to protect 39 million workers, potentially preventing 120 deaths and 60,000 injuries annually.

Implementation
Requires energy isolation devices capable of being locked in the "off" position, formal de-energizing procedures, and employee training.

ROSS L-O-X®/EEZ-ON® Valves
These valves offer shut-off certainty and gradual pressurization, designed for easy installation and cost efficiency.

Overview
The document provides technical specifications and operational procedures for ROSS valve models, designed for controlling air flow in pneumatic systems.

Specifications

Ambient Temperature: 40 to 120°F (4 to 50°C).
Media Temperature: 40 to 175°F (4 to 80°C).
Flow Media: Filtered air with a 5-micron filter recommended.
Inlet Pressure: 15 to 150 psig (1 to 10 bar).
Port Threads: NPT standard, with options for parallel G threads.

Valve Operation

L-O-X® Valves: Feature a red handle for visibility, allowing quick shut-off and exhaust of downstream air.
EEZ-ON® Valves: Allow gradual pressure build-up before full flow.
Solenoid Pilot Valves: Enable remote control of air flow.

Model Numbers & Dimensions
Lists various valve models with port sizes, flow coefficients, dimensions, and weights.

Installation and Safety

Ensure electrical supply is off and the pneumatic system is exhausted before servicing.
Installation and servicing should be performed by trained personnel.

Key Features

Quick response due to poppet construction.
Capability to integrate with silencers for noise reduction.
Energy isolation devices, not emergency stop devices.

Installation and Maintenance
Regular checks and maintenance are essential. Overhauled or serviced valves require functional testing before installation.

Product Specifications
ROSS products must be used within specified limits, and only ROSS parts should be used for repairs.

Filtration and Lubrication
Air systems should have a 5-micron filter. Use compatible lubricants to avoid damage.

Air Flow Restrictions
Avoid restricting air flow to prevent erratic valve action. Silencers must have adequate flow capacity.

Power Presses
Pneumatically controlled machinery must use a press control double valve with a monitoring device for safety.

Energy Isolation
ROSS L-O-X® products are energy isolation devices, not emergency stop devices.

Accessories
ROSS MUFFL-AIR® silencers reduce noise with minimal back pressure.

Warranty
ROSS products are warranted against defects for one year. Misuse or improper maintenance voids the warranty.

ADJUSTING NEEDLE INLET PRESSURE REMOVED AIR PRESSURE TO INLET VALVE OPENS TO FULL FLOW When inlet pressure is removed, the exhausting downstream air pressure keeps the inlet poppet open until the downstream pressure drops by approxi- mately 90 percent. The remaining pres- sure is exhausted via the delay orifice. When air pressure is first applied to the inlet, air flow to the piston is restricted by the adjustable needle in the delay orifice. Downstream air pressure gradu- ally builds up at a rate determined by the setting of the adjustable needle. When downstream air pressure reaches approximately...
