Actuation Options and Button Styles

Pushbutton Valves

Pushbutton-actuated valves provide precise, ergonomic control for operator-intensive applications. These valves feature spring return mechanisms that automatically revert to their default position when button pressure is released.

Button Types:

• Flush Button: Low-profile design minimizes accidental actuation
• Mushroom Button: Enlarged surface area for easy palm operation
• Guarded Button: Protected actuator prevents unintended valve shifts

Color Options:

• Green buttons: Typically indicate "start" or "run" functions
• Red buttons: Commonly used for "stop" or emergency functions
• Color coding improves operator recognition and safety compliance

Palm Button Valves

Palm button valves require deliberate hand pressure across a large surface area, providing an additional safety factor in operator control applications. The design ensures intentional actuation while remaining comfortable for repetitive use.

Standard Palm Button Features:

• 2.67" x 2.47" actuation surface (Series 12)
• Smooth, non-slip surface texture
• Requires sustained pressure to maintain valve position
• Available in green or red color options
• Compatible with ring guard accessories

Heavy-Duty Palm Button Valves

Heavy-duty palm button valves incorporate reinforced construction for extreme industrial environments where standard valves may fail prematurely. These valves withstand harsh conditions including vibration, temperature extremes, and high-cycle applications.

Enhanced Features:

• Reinforced die-cast aluminum body construction
• Extended temperature range capability (-10°F to 175°F)
• Dual mounting flange system (side and bottom)
• Ring guard protection available as accessory
• Weight: 1.8 lb (0.8 kg) for stable mounting
• Dimensions: 3" L x 2.67" W x 2.47" H

Installation and Mounting Configurations

Inline Mounting

Inline mounted valves integrate directly into pneumatic line runs, providing compact installations where space is limited. Threaded port connections simplify installation and allow tool-free reconfiguration when system changes are required.

Inline Mounting Benefits:

• Minimal space requirements
• Direct line integration
• Reduced fitting count
• Lower pressure drop
• Simplified plumbing layouts

Flange Mounting

Series 12 heavy-duty valves feature bottom and side mounting flanges that enable secure attachment to machine frames, operator stations, or custom mounting brackets. This configuration provides superior vibration resistance and operator ergonomics.

Mounting Specifications:

• Bottom flange: Pre-drilled mounting holes
• Side flange: Alternative mounting orientation
• Bolt hole spacing: Consult dimensional drawings in catalog
• Mounting hardware: Not included (standard industrial fasteners)

Port Threading Options

NPT (National Pipe Thread):

• Standard American pipe thread taper
• Available in 1/8" and 1/4" sizes
• Requires pipe thread sealant or tape
• Standard model numbers (no prefix)

BSPP (British Standard Parallel Pipe):

• Parallel thread design with sealing washer
• ISO 228 compliant (G-thread designation)
• Available in equivalent metric sizes
• Model numbers prefixed with "D" (e.g., D1223B2001)

Performance Characteristics and Flow Data

Flow Coefficient (Cv) Values

The flow coefficient (Cv) indicates the valve's flow capacity, representing the volume of water (in gallons per minute) that passes through the valve with a 1 psi pressure drop. Higher Cv values indicate greater flow capacity.

Series 11 Cv Ratings:

• Pushbutton models: Cv 0.5 to 0.6
• Palm button models: Cv 0.5 to 0.6
• Suitable for small to medium cylinder applications

Series 12 Cv Ratings:

• Heavy-duty models: Cv 0.8
• Enhanced flow for larger actuators
• Supports high-cycle applications

Response Time and Valve Speed

ROSS manual valves utilize poppet or spool construction designs that deliver rapid response when manually actuated. The valve shifting speed depends on operator actuation force, internal spring tension, and system pressure.

Response Characteristics:

• Near-instantaneous shifting upon actuation
• Spring return time: Dependent on spring constant and pressure
• No electrical delay (purely mechanical operation)
• Consistent performance over millions of cycles

Operating Distance for Valid Actuation

Valid Operation Distance: 0.22 inches (5.5 mm)

• Button must travel this distance to ensure complete valve shift
• Ensures positive engagement of internal valve elements
• Provides tactile feedback to operator

Invalid Operation Distance: 0.04 inches (1.0 mm)

• Insufficient travel for reliable valve operation
• May result in incomplete shifting or valve chatter

Frequently Asked Questions

Q: What is the difference between NPT and BSPP threading?
A: NPT (National Pipe Thread) is a tapered thread standard common in North America, requiring pipe sealant. BSPP (British Standard Parallel Pipe, or G-thread) uses parallel threads with a sealing washer. BSPP models are prefixed with "D" in ROSS model numbers.

Q: Can these valves be used in hazardous locations?
A: Standard manual valves are not rated for hazardous locations. However, ROSS offers specialized products for explosion-proof and intrinsically safe applications. Consult ROSS engineering for hazardous location requirements.

Q: What air filtration level is recommended?
A: ROSS recommends 5-micron filtration for optimal valve performance and service life. Proper filtration prevents contamination damage to internal seals and moving components.

Q: Are replacement parts available for older valve models?
A: ROSS maintains extensive spare parts inventory for current and legacy products. Contact ROSS with your specific model number for parts availability.

Q: Can I convert an NPT model to BSPP threading?
A: Threading is integral to the valve body and cannot be field-converted. Order the correct thread type for your application using the appropriate model number.

Q: What causes the valve to leak air from the exhaust port?
A: This is normal operation when the valve is actuated. 3/2 valves exhaust through port 3 during shifting. Continuous leakage when not actuated indicates worn seals requiring replacement.

Q: How do I determine the correct Cv value for my application?
A: Cv sizing depends on cylinder bore, stroke length, cycle time, and available pressure. The catalog includes sizing formulas, or contact ROSS engineering for assistance.

Q: Are these valves compatible with ROSS double valve systems?
A: Yes, ROSS manual valves are commonly used as pilot controls for DM2® Series, SERPAR®, and CrossFlow® double valve safety systems in press and machinery applications.
