Chapter 18 Valves and Specialties

This chapter covers labor and price tables for valves and

specialties in pressure type piping systems as follows:

Standard Valves:

• Bronze Valves, Threaded and Soldered, 125#, 150#,

300#

• Iron Valves, Flanged and Welded, 125#, 150#, 250#

• Ductile Iron Valves, Flanged and Grooved, #200

• Plastic PVC Valves, Socket, Threaded and Flanged

• Carbon Steel Valves, Threaded and Welded, #250,

#1000

Specialty Valves:

• Strainers • Control Valves

• Steam Traps • Pressure Valves

• Gas Valves • Temperature Control Valves

• Balancing Valves • Gas Valves

Specialties:

• Hot Water • Refrigeration

• Chilled Water • Steam

Units

All diameters are in inches.

Flanges and hangers are covered in chapter 17.

Labor

The labor productivity rates in the tables are what

the average mechanic under average conditions can erect

on lower fl oors of construction projects However, they

may require the application of labor correction factors for

variable conditions such as upper fl oors, higher piping

runs, congested spaces, etc.

The labor in the tables are in hours per piece and

hours per foot for pipe.

Pricing and Discounts

The pricing in the tables are based on the typical manufacturers list prices and the contractor’s supplier discounts must be applied.

Appropriate price discounts can range from roughly

10 percent to 80 percent dependent on the following:

• Supplier discount structure

• Who manufacturer is

• Size of batch involved

• Availability

• Shipping distance, costs

Not All List Prices Are Publicly Available

Where there are no prices listed in tables, they are not usually publicly available from the manufacturer If there is neither labor nor prices listed for a particular di-ameter in the tables, the particular item may not be avail-able or it may not be a commonly used item.

Caution With List Prices

Pricing can sometimes vary signifi cantly because of changes in commodity material pricing such as copper, etc Periodic checks of current list prices should be made.

If in doubt about your discounts from list prices,

check with your supplier as to what they are for the various

categories of items - or request a quotation.

Automatic Updating Available in Wendes Computer System

Automatic updating of list pricing is available in the

Wendes Computerized Piping Estimating System Call (847)
